It is raining. No anting for me ;(

 

Pseudoneoponera rufipes 

2Q
After catching another queen in late August as well as the older other queens not doing much, I decided to make a risky move and merge them all together (if you can't tell this is a way i use to reduce colonies). After a few days together one queen collapsed but not due to dominance related injuries. A hierarchy emerged between the remaining two queens. 

Here you have the two. The one closer to the camera is the dominant one, and the submissive one gets constantly bullied by the dominant queen. Usually in the form of antennae bashing and pulling. Yet, this is the most successful they have been as I have not seen that many eggs at once in this year of keeping them.

 

Iridomyrmex anceps

1Q, ~300W

They are getting out of control. They move extremely fast and react quickly to any disturbance. It does not help that they are the second fastest growing species in my collection (beaten by Pheidole, but the big heads move way more chill compared to the black tyrants).

 

They also like to make pyramids using brood items in the arena. It could be that the drier environment in the arena favours the pupae more.

 

Myopopone castanea 

1Q

Finally the eggs hatched, but that old larva from before is still the same... I also moved her to a nest with forest substrate instead of clay. It will likely take another month for workers to arrive, if I am lucky that is.

 

Anochetus graeffei 

3Q, ~30W

Now moved them to a plaster nest. So far so good with them, good number of cocoons and the workers bringing the larvae outside for food.

 

But just one problem. Mites. I saw a few workers having some attached on their bodies. See the bumps on this worker's gaster?

No idea if these are parasitic and harmful to the ants or just hitchhikers that does nothing. I will keep an eye on any worker deaths.

 

Paratopula bauhinia
~20W

This is my old colony which I got back from Leo. From an incident a massive number of workers died and presumably the queen too. However, there are some eggs lying around and there is one wingless dealate in the mass of alates that could be the queen. 

 

There is really only about 20 to 30 workers, the rest are alates.

 

Carebara affinis

1Q, ~100W

Good to see the first major arriving, visible above the queen's head. The colony is growing well but a bit slow. That is probably a blessing in disguise, watching 50 workers rush to the tube entrance during feeding time is terrifying and it will only get worse.

 

 

There has been some deaths. Mayriella is on the brink of collapse with workers dropping like flies. Centromyrmex queen gave up and died after I moved her to a new setup which is a big bummer.

University is hammering on me, but I did get to try some lab work on sorting insects which is very neat. See you all next time.

 

 

 

 

 

 

[GOCAMPONOTUS]

Just stunning ants!

[RushmoreAnts]

Nice to see some unique species! I love those Pseudoneoponera. They look so... primal.

I had an entire week off...

 

Pheidole nodifera

1Q, 1000W

Got my DIY engine up and running again and made them and Iridomyrmex some ytong nests.

 

However, the problem of the brick being too dry struck and they suffered quite a bit, about 100 workers died of dehydration. It wasn't until me looking at the nest and saw the larvae all wrinkled that I realised the issue. The problem has been resolved now with me blasting the nest with water and putting a water tube in the arena.

 

Iridomyrmex anceps

1Q, 500W

This is their ytong nest.

 

They are more dry tolerant than Pheidole but it was obvious that they needed water. Now they actually put the majority of the brood in the water tube next to the nest.

Here is a few chambers with brood right up against the glass. 

 

Tetraponera nigra

1Q

Found this queen maybe 2 weeks ago. She is laying eggs which is astounding (a lot of the tponera queens I caught never did anything).

I haven't actually been feeding her protein so I should give her more roaches. I do want to keep this species so fingers crossed.

 

Camponotus sp.

1Q, 5W

These and my big colony are actually the same species. I likely will give them away soon. Still, they are pretty cute.

 

Myrmoteras binghamii

1Q,15W and 1Q, 10W

The formicinae trap jaws are back! Got 2 colonies again. This time I am keeping them quite well with the brood actually developing and not stagnate (all thanks to the fridge).

 

You might ask why one colony is in a chamber and why the other isn't. Answer is that one just never moved so I removed the chamber. They don't really mind.

Here is a video from a month ago where the chamberless colony eats some roach pieces.

 

Odontoponera denticulata

1Q, 2W

I removed a queen to see if the behavior of killing pupae was related to some sort of between-queen sabotage. It has been about a week and this cocoon is still here. If it dies then I will switch the other queen back to see if there is any difference.

 

The viewing plastic isn't the best...

 

Harpegnathos venator

1Q, 13W

Everyone's favourite curved jaw Myrmecia is developing very well. Harps grow surprisingly quick even with them being largish ants.

 

Spiky larva.

 

Camponotus lianghuang

1Q 

I saved the best for last. This rare species of Camponotus flies in October, which is very late for the genus. I caught this queen last week after seeing a male while at university. The best part is that she already laid 2 eggs.   

 

They are still undescribed but the name "lianghuang" is given to them by sellers and keepers. It means bright yellow which perfectly describes the ant.

 

I managed to bump into Dr. Guénard while working at the lab and he complimented my shirt. So yeah, consider this a brag   

The anting season is coming to an end but some Polyrhachis and other random things is still flying. I was shocked to hear US and EU keepers already starting diapause. Maybe I just never noticed. Ants here do diapause in or even after November so my ants still got some time to grow.

Hope you have enjoyed this entry and I will see you next time.

2nd November 2024

It is getting cooler...

 

Odontomachus simillimus (1Q, 11W)

Growing very nicely. It feels like their meat demand decreased as they grew? The workers are still nanitic size and the next generation should give rise to the bigger workers.

 

Worker next to the large egg pile.

 

Odontomachus silvestrii (1Q)

Haven't laid a single egg yet. Her gaster seems to have gotten longer for the last few days, maybe a good sign?

 

Ectomomyrmex leeuwenhoeki (1Q, 9W)

Gave them a new nest. I added too much water in the previous setup and some pupae died, rip.

 

The two queens are still here and they will likely grow a bit more judging by the eggs and larvae present.

 

Colobopsis minus (30W) and hybrid (10W)

The three queen minus colony are booming. I spotted a few major pupae/larvae and that is very exciting.

 

The hybrid colony is not as fast by a long shot. They suffered a few worker deaths for some reason. Still, they have a nice pile of brood.

 

Polyrhachis peetersi (1Q)

3 eggs. Is nice. She is still very timid but disturbing her doesn't cause her to eat the eggs so that is fine.

 

Camponotus mutilaris (1Q, 7W)

I almost forgot to feed them, which tells you how much of a background character they are. The queen finally laid a few eggs but they are growing at snail's pace.

 

Ooceraea biroi (400W)

I have split them, the left colony is around 100 workers while the rest is at the dirt setup. They also have mites but I have given up on dealing with that.

 

This is the split colony. Waiting for them to lay eggs again.

 

I actually got a new Camponotus colony. Not sure on the species, they are darker than my old vitiosus, but there is a chance my old vitiosus is actually lighti. After evicting them from their sticks I realised they don't have a queen. However, I noticed eggs appearing so that means the queen is there or the workers are laying. Anyways I might include them in the next update. 
See you next time.
