how many workers did your colony have before they made repletes

@Unfrozen I am unsure if Nathant will respond as he's not as active anymore...

 

I've been keeping a colony since 2017 (just laid her 3rd batch of eggs in June.)  The first workers are capable of being repletes, but don't store a lot.  Not much really happens their first season.  In their second season, they usually start laying the first non-nanitic workers and have a bit more size to them.

 

P. imparis is a relatively easy species to keep if you remember these facts...

  • They grow very slowly if you start with a single queen colony
  • They are expert escape artists and can climb over fluon (lost a good chunk of this colony to the room...)
  • Northern varieties have typically two diapause events, one in the late Spring, the other in the Winter
  • Southern varieties tend to have diapause that can last for up to 9-10 months of the year!
  • It's often easy to tell when diapause start/stops as they will stop in activity, often closing off the next entrance. Typically taking in a LOT of proteins and sugars before they do.  
  • They often only lay eggs in a few batches once a year (at least the Northern ones I've observed.)
  • Unlike most ants who require proteins after they have brood, P. imparis need proteins *before* their diapause in the summer. They store the proteins in the repletes, and the brood is fed entirely off the repletes until diapause is over (can be a tense time if they have insufficient reserves.)
  • I believe it's a myth they need to be kept at cold temperatures during the summer. I've kept the colony successfully at 75-85F in the summer, and they have laid and had brood
  • Both times my queen laid again, her she gorged on foods, and her gaster swelled considerably, then she laid a few batches of eggs during the summer diapause
  • I do a winter diapause of 2-3 months at 45F with the rest of my ants, Dec 1- Feb1 typically.
  • They are opportunistic feeders and I find not very picky for sugars or proteins

Hope this helps :)

what's your worker count? couldn't get mine to surpass a year and a half

Terrible… I made two mistakes that really stunted their growth.  Their first season in 2017 the cabinet where I keep the ants had an A/C vent behind it, took me a bit to realize the vent was blowing cold air thru a couple of holes into the cabinet and chilling everything in there.  She (and most of the queens of other ants I had that season) barely laid any thing. The first season I think it was *August* before her nanitics eclosed, comparedto that to early July for this seasons queens (she had maybe 3 or 4 workers in total).  The second big mistake was I noticed the worker count was dropping, and I couldn’t figure out why.  Turned out the screen I had affixed to the back of the outworld tub had come loose, so they were wandering off into the room and lost forever… So I think I am down to about a dozen now, the high was in the 20s last year before I lost them.

 

Here’s what she looked like entering diapause, you can see how much her gaster is swollen preparing to lay again this season:

Here’s a quick pic last night of the brood development, I think it will get me back to 20+ or so workers again if I don’t mess it up again :)  Hopefully by next season if she makes it, she’ll have a chance to finally build the numbers.

Hey guys. I know some might be excited to finally hear from these colonies again but it won't be what you're expecting. Sadly these ants are no more as I lost interest in the hobby. But I've kept telling myself I'm going to find some more  P. imparis queens next year and start the hobby again. So stayed tuned... for 8 months, haha.
