 What yellow mellow ants eat


In captivity, you can feed yellow meadow ants protein-rich food and sweets twice a week. For example, you can feed them live insects or protein jelly on Mondays and Fridays, and sweets, organic honey, or fruit on Wednesdays and Saturdays. Honeydew, is a sweet liquid produced by aphids that yellow meadow ants farm underground. Yellow meadow ants need protein to develop properly, and they get. it from foods like fruit flies, crickets, and mealworms.Yellow meadow ants love sugars like honey and sugar water. Yellow meadow ants can eat fruit like half a grape or a similar amount of banana. You can feed yellow mellow ants protein-rich foods like insects, eggs, and commercial ant food. Hard-boiled eggs are a good source of protein for ants. This love of sweet liquids also carries over into captivity, as these ants absolutely LOVE sugars (honey, sugarwater).  Feed SMALL drops of sugars as these ants are prone to drowning in liquid. As these ants are used to having sugars constantly in the wild, it is important that you offer sugars multiple times a week. The queen should always have a somewhat plump gaster. If you are feeding your yellow meadow ants hard-boiled eggs, you should give them the yellow part (yolk), as it is the more nutritious protein source compared to the egg white; most ant keepers recommend feeding the yolk when offering hard-boiled eggs to ants.

 hibernate from late October to late March. This period of dormancy is called diapause.

 What they need to live and like to live

They hibernate during the winter at temperatures around 5–10°C (41–50°F). 

Outworld Temperature
The ideal temperature for the outworld of yellow meadow ants is between 18°C and 28°C (64°F to 82°F).

Nest Temperature
Yellow meadow ants (Lasius flavus) prefer their nest to be at a temperature around 20-25°C.  (68-77 degrees Fahrenheit)

Humidity
Yellow meadow ants  prefer a humidity level of 50–70% in their nests.

 Outworld humidity:Yellow meadow ants  need an outworld humidity level of 30–80%. They prefer humid environments and thrive in high humidity. 

To control the humidity for an ant colony, use a hygrometer to measure the current humidity level, then adjust by adding a water source like a damp sponge or misting the enclosure if it's too low, and increase airflow or use a drier substrate if it's too high; regularly monitor and adjust as needed to maintain the optimal humidity level for your specific ant species. 

Nesting
Yellow ants prefer to nest in moist soil, under rocks, or in decaying wood. They can also nest in leaf litter, woody debris, mulch, and other materials.   

Light Level; Yellow meadow ants (Lasius flavus) prefer low light levels (in the nest) because they are subterranean ants. They are most comfortable in their underground nests, where they are protected from predators and the sun. 

Yellow meadow ants, also known as Lasius flavus, prefer low light levels in their outworld as they are a subterranean species, meaning they naturally live underground where light is minimal; therefore, a dimly lit environment is best for their enclosure. 

Cleaning: Clean their habitat weekly to remove waste and uneaten food. You can also spot clean as needed. 

 

how to make sugar water

To make sugar water for ants, mix one part sugar with four parts water; essentially, dissolve a single portion of sugar in a larger amount of water to create a dilute, runny solution that ants can easily access and drink from. 

Key points to remember:

  • Dissolving sugar: Stir well to ensure the sugar completely dissolves in the water. 

  • Freshness: Replace the sugar water frequently as it can ferment quickly. 

  • Serving method: Offer the sugar water in a shallow dish or container that allows ants easy access.



Heating methods

To keep an ant colony warm, the best method is to use a heating pad or heat cable specifically designed for reptile enclosures, placed underneath the formicarium, allowing the ants to regulate their temperature by moving to different areas of the nest depending on their desired warmth level; ensure to monitor the temperature closely and provide a temperature gradient within the nest to avoid overheating any part of the colony. 

  • Heating method:
    Heating pads or heat cables are generally preferred as they provide a consistent heat source. 

  • Temperature regulation:
    Use a thermostat to control the temperature and maintain a stable environment. 

  • Gradient within the nest:
    Allow for different temperature zones within the formicarium by placing the heat source only under a portion of the nest. 

  • Monitoring is key:
    Regularly check the temperature to prevent overheating.


 Mating season requirements  for if you want to find a new queen

Yellow meadow ants mate in the summer during nuptial flights. These flights typically occur in late July to August, after significant rain. 

Mating season requirements

  • Winged adults: The winged adults of the yellow meadow ant pair and mate during the summer.

  • Fertilized queens: After mating, the fertilized queens shed their wings and find a place to start a new colony. 

  • Males: The males die shortly after mating. 





Colony founding

  • Polygynous colonies: Some colonies can be polygynous, meaning they have multiple queens.
     

Yellow meadow ant habitat

  • They build small mounds in lawns, and larger mounds in fields and meadows. 

  • They forage below ground for small insects and mites. 

 

 Warnings For beginners

Yellow meadow ants rarely forage outside of their nests

When keeping yellow meadow ants (Lasius flavus) as a beginner, be aware that they require a specific, mostly underground habitat, are sensitive to disturbance, and need a consistent temperature and humidity level; avoid gel ant farms, direct sunlight, and frequent handling, as these can stress the colony and lead to potential health issues; always research proper care before acquiring a colony. 

Key warnings for beginner yellow meadow ant keepers:

  • Minimal disturbance:
    Yellow meadow ants are sensitive to vibrations and disturbances, so handle the formicarium gently and avoid tapping on the glass. 

  • Research is key:
    Before acquiring a yellow meadow ant colony, thoroughly research their care requirements to ensure you can provide the best environment for them. 

  • Monogynous colonies: Once a colony is established, the queens will kill each other off until only one is left.  If there is more than one queen

Yellow meadow ant colonies can die off due to a variety of factors including: disruption of their nest environment, lack of food sources, to their soil nutrient levels due to their own mound-building activity. 

 In the wild they live almost entirely off honeydew

 



How to Keep an Ant Colony

Foreword

     It’s always best to talk to a more advanced keeper, as they’re likely to have already gone through similar experiences and developed solutions. There are many online groups of ant-keepers who are willing to help. ​

     It is important to note that gel ant farms are not sufficient for keeping ants. The sugary gel makes them comparable to a person living in a gingerbread house. Though they can keep worker ants alive for maybe a few weeks, proper colonies will quickly die off. Sand/dirt farms can keep colonies alive, but are generally not advisable due to a range of problems, namely the risk of chambers collapsing and the low visibility which makes it harder to both enjoy and maintain the health of your colony. Solid formicaria are the best option for your ants. These are typically made of a tough plaster or carvable substance with premade chambers the ants live within. They should be absorbant, to allow water to soak into the nest providing humidity. Formicaria made out of high-quality materials also have the added advantage of resisting mold growth and chewing, increasing the longevity and security of the nest. Most of the cheap plastic farms from Amazon are NOT good!

​​Though your colony may only have a few worker ants right now, this is because it is only in its infancy. With correct care (ideal heat, feeding, and hydration) your colony can optionally grow to be just as large as wild ant colonies! Ants will only cooperate with other ants who are from the same colony, so ants from outside (even if they are the same species) should never be introduced to your colony.

The Queen Stage

Most species begin with queen(s) on their own. This is called the founding stage. 

 

Founding Methods

     There are multiple methods of colony founding, and which one your queen uses depends on its species.  yellow meadow ants (Lasius flavus) are fully claustral

 The most common method is fully claustral founding. This term is derived from the name of the queens’ founding chambers— the claustral cell. A queen being fully claustral means that in the wild, she doesn’t need, nor want to leave her claustral cell. For most species, simply put your queen in a test tube setup and wait for her nanitics—or first generation of workers—to eclose. She raises these workers off of fat stores created by breaking down her now-useless wing muscles. Your queen does not need to be fed during the founding stage if she is fully claustral, and doing so could stress her out. For these queens, they should not be disturbed more than once or twice a week, as too much disturbance could stress the queen out. Doing so may cause her to eat her brood (eggs, larvae, and pupae). Instead, once she has workers, you can feed them immediately. Do NOT move your queen into a larger setup before she has workers! It is often advantageous to the health of the colony to keep them in the tube as long as possible. Larger colonies tend to be much healthier when moved.  yellow meadow ants (Lasius flavus) are fully claustral

     The second most common founding method is the semi-claustral method. These queens cannot raise their first generation purely off of their wing muscles and must forage for food to raise their nanitics. During this time and depending on the species, it is important that the queen is fed protein and sugars. Sometimes feeding weekly is enough, other times twice a week is better. Before the queen has larvae, you’ll want to feed small amounts of protein (fruit flies are great for this!). However, once she gets larvae, you’ll want to feed more. It’s almost always better to overfeed than underfeed, just make sure you don’t allow old food to mold up and cause issues. Remove trash when you can.

     Semi-claustral queens can be raised with an outworld, but it’s typically better for the queens to simply feed them in a founding test tube setup. 

     The third founding method is social parasitism. A full guide for social parasitism will not be covered here, because it is extremely complicated and methods vary from species to species. Social parasites are not for beginners. 

 Keeping a Colony

      Now that your queen has her first workers in a test tube setup, you’ll need to keep the colony fed and growing. Depending on species, your colony could grow very quickly or somewhat slowly. How long your colony stays in a test tube is dependent on this; generally, it is beneficial to allow a colony to fill up its tube before moving it out into multiple tubes or a larger nest. 

     Once your colony begins to grow and feeding becomes difficult in the test tube, you may need to consider an outworld. An outworld is where the ants forage for food and functions as the outside world. Outworlds can come in a variety of sizes, and can be homemade from containers. When your ants are using their outworld, it can get pretty dirty, since they'll put their waste outside for you to clean up. Whenever you can, remove existing trash or leftover food from the outworld to prevent mold or trash buildup. 

     An outworld without a barrier can just become an extension of the nest. You need to make sure that ants cannot crawl out and escape from their contained setups. For this, you need a barrier. Barriers are bands—typically of Fluon or talcum powder—applied to the lip or walls of your outworld, making the surface slippery which stops ants from escaping. 

     So, how do you connect your test tube to the outworld? Well, you can use vinyl tubing to connect your test tube to a port drilled in the side of the container, or you can simply place the test tube into the container and take off the cotton. The ants should be able to easily access their nest and outworld, so it may be a good idea to put the tube up against a wall so they can find the entrance. However, make sure that there isn't too much airflow into the test tube. Most ants want smaller entrances and will do worse if they feel like they're nesting in the open. Make sure to not overcomplicate the outworld with anything that could have harmful chemicals, such as many colorful decorations. Sometimes plain plastic or plaster is best! Dry outworlds can be harmful and cause smaller ants to desiccate, so make sure their setup is humid. Sand at the bottom of outworlds can make this problem worse.

Light Method

     Simply shine a light or expose your colony to light while they are attached to a new nest via tubing or tape, and keep the new nest dark. Make sure the light isn’t too hot. The ants will hopefully begin moving within a few minutes of discovering the new home, and once they’re done, detach the old nest and dump out any stragglers into the outworld. It may take some time (possibly hours or days) for the ants to decide that the new nest is a good home.

Sunlight Method

     The sunlight method is a step up from the light method. Some ants can withstand regular indoor lights, but sunlight is usually much more bothersome to them. Expose the old nest to sunlight while keeping the new nest dark. Pay attention to the temperature of the nest, and be careful to not let the sunlight cook any ants.

Leaf cutter ant

 

 

Leafcutter ants eat a fungus that they cultivate in underground gardens. They grow the fungus by feeding it a compost made from leaves they cut. How they grow the fungus is They cut leaves from plants then they carry the leaves back to their underground nests and cut the leaves into small pieces then they inject the leaf pieces with a fungal secretion The fungus breaks down the leaves into an edible mushroom form why they grow the fungus the fungus breaks down plant polymers that the ants' digestive enzymes can't This makes the plants more nutritious for the ants. Leafcutter ants are found in Latin America and the Caribbean; they live in the forest floor and construct underground chambers. Leafcutter ants use vibrations to communicate with each other they can send vibrations through their jaws into the leaf, which travel down the stem to nearby nest mates

 How to feed them

 Give them leaves, that is it they do the rest on their own

Nest temperature

Leaf cutter ants prefer a nest temperature between 23°C and 26°C (73°F and 79°F), as they are accustomed to a very stable underground temperature in their natural tropical habitat, with minimal variation throughout the year. 

Key points about leaf cutter ant temperature preferences:Stable temperature: They thrive in a consistent temperature range, with minimal fluctuations. Tropical climate: Since they originate from tropical regions, they prefer warmer temperatures. Underground nesting: Their underground nests naturally help regulate temperature. 

 Outworld temperature

Leafcutter ants prefer an outworld temperature between 24°C and 26°C (around 75°F to 79°F), as they are typically found in tropical environments with relatively stable temperatures; ensuring their nest area is also within this range is crucial for optimal health and activity. 

Key points about leafcutter ant temperature preferences:Stable temperature: They thrive in environments with minimal temperature fluctuations. 

   Humidity

Leafcutter ants prefer a humidity level of 85–95%. 

ExplanationLeafcutter ants are native to the tropical regions of South America, where they live in lowland shrubs and foliage. They thrive in environments that mimic their natural habitat, including the right temperature and humidity. When kept in captivity, the humidity level should be measured directly where the fungus is located. Cold surfaces can act as dehumidifiers, so condensation may form on the glass of an enclosure. 

 Cleaning  Stuff should be the same as the Yellow Meadow ant

 

 

 

Could you guys also give me advice on what ant I should do next And advice on the Yellow Meadow Ant

Just some thoughts:

 

One: I would consider shortening this guide on parts like the different queen ant founding stages, since most ant keepers with a bit of experience would probably already know about that stuff

 

Two: maybe u could edit and fix some spelling and writing errors

When catching an L. flavus queen, they look just like the workers, but they have more yellowish legs and they have a very yellow patch under their abdomen, also I just wanted to say that you do not need to cover their nest, instead leave it open, the ants get used to it and they won’t get stressed when you check on them.

1x Formica subsericea, 20+ workers + wait, SMALL BROOD PILE? IN FEBRUARY?!? :thinking:

1x Crematogaster cerasi 2 workers with brood (still growing)

I don't think I've ever seen someone so hell-bent on obtaining Lasius, haha. They are very cool looking, but there are also lots of other yellow and orange ants out there!

Alright, lasius does not need anything special to keep them, just get them an outworld and a nest that fits the colony, not too much space but also not too little because too much space could stress them out and too small prevents growth, feed them until they look full or until your satisfied, you can tell if they are full because lasius likes to fill themselves up and they love to eat (my experience). Give them a constant source of fresh water and sugar, that is all you need to do with keeping lasius, nothing special, but they can be a very rewarding species to grow.

 

also, whenever lasius workers escape, they always return to the nest and it is almost like they are saying “Mama, let me in!” It is only bad if the queen escaped. Another pointer is that they are very hardy so if you make a mistake or have a big die off, with the correct care, they can and will bounce back in numbers.

 

hope that you find this species fun to keep!

Hello ant1234;

Lasius flavis is the name given to these ants in Europe etc, Lasius brevicornis is the North American counterpart. Pardon the lack of italics, my iPad doesn’t have that option.

These ants are considered subterranean, collecting food and honeydew below ground essentially. My best tip for you to help a founding colony is to cover their food so they can forage “underground”. I’ve even fed them in a small hole beside the nest and covered it after feeding. I was surprised how much more protein they would take when fed this way. I’ve also found this feeding method works well with founding colonies of other ants, especially when the colony is small and the ants are shy.

There are many factors that affect the development of a colony. I think every successful colony in captivity is special.

I agree. To a previous user, let's not bash someone for really desiring to have an ant that some consider "boring". Every ant species is so fun to keep, no matter what kind!
