Here is my small nervous Formica subsericea. These are black field ants, you can tell them from carpenter ants because they are shiner, only come in one size (no majors with big heads) and their thorax has a dent rather than a hump. They also move differently from carpenter ants which tend to be more deliberate and less spastic.
Today I gave them fruit flies and they have eagerly piled them up in front of the queen. Who looks like she just wants to go to sleep.
Even the queen moves quickly. They are always fighting over who gets to carry what. There is generally a small clutch of eggs in the nest and I have never seen them set it down. An ant is always proudly holding the cluster of new eggs and she won’t let her sisters help her hold it. I think they must sit it down when it’s dark and quiet in the nest— but if I’m taking photos? well we never get to see them calm first that reason! Ants notice photographers! #formica#ants#antvideo
"workers are not simply scaled-down versions of queens that have lost their wings."
"Instead workers have a distinct thorax architecture with an enlarged muscle system to strengthen the neck and increase the range of motion of the head ... appears to be a key adaptation to allow ants to lift and carry objects or prey that are many times their own weight"
My Camponotus discolor colony has produced a batch of chunky queens. They all eclosed on the same day. I wonder when they fly? Alates are a mixed blessing for ant keepers— they can really drain the energy of a colony and may lead to its end. But, it’s beautiful to watch. Seriously considering mailing these girls back to Tar Heel ants in GA —. who sold me the queen. They are legal in NY but it’s too far north to let them fly. He has many colonies— maybe he could find a way to get them mated.
They are such beautiful ants! You almost forget how ravenous, warlike and sneaky they are!
The queens are all about the same shade of yellow/orange— which shows they all emerged at once. As their exoskeletons harden, their color will darken. In this species the wings are almost black—very striking! I hope the next batch isn’t all males— though this colony is massive— to think there were only 8 of them years ago.

Quick Tulip update: Didn’t see her for a few days and started to worry since she getting up in years for an ant. Just spotted her in the lower chamber doing some patrolling around. She’s at least two years old. Still full of life. #namedAnts#tulip#ants#tuliptheant
Ooof. Never argue with an ant colony. Cleaning out a storage box in the garden. One corner has an ant colony in it, partially destroyed by my clearing. Also present: Two 3cm-ish false widow spiders, shiny black. Can't escape the box now the contents have been removed, sides are too smooth.
Left the job and went to have lunch, expecting to need to re-home the spiders. Figured they had plenty of ants to eat. On return, no sign of the smaller spider. The larger has had a disagreement with the ants. It has not ended at all well for the spider.
" Allopeas myrmekophilos was regularly found in colonies of the ponerine army ant Leptogenys distinguenda. The gastropods always remained inside the bivouacs of their hosts, where they were able to move around undisturbed by the ants. During emigrations A. myrmekophilos was always carried by workers in a manner identical to brood or prey items." https://link.springer.com/article/10.1007/PL00012646
Simply putting colored paint on a few ants has let me discover that individual ants have certain spots they like best — Tulip likes to be on the highest point of this branch. If I don’t see her there I get worried. She’s a little camera (light) shy so documenting how often I see her in the same spot has been a challenge. She has preferred this spot for at least a whole month. Here are a few times I caught here there.
The honeybee brain hosts over 600,000 neurons, at a density higher than that of mammalian brains:
"Our estimate of total brain cell number for the European honeybee (Apis mellifera;
≈ 6.13 × 10^5, s = 1.28 × 10^5; ...) was lower than the existing estimate from brain sections ≈ 8.5 × 10^5"
"the highest neuron densities have been found in the smallest respective species examined (smoky shrews in mammals; 2.08 × 10^5 neurons mg^−1 [14] and goldcrests in birds; 4.9 × 10^5 neurons mg^−1 [16]). The Hymenoptera in our sample have on average higher cell densities than vertebrates (5.94 × 10^5 cells mg^−1; n = 30 species)."
Ants, on the other hand ...
"ants stand out from bees and wasps as having particularly small brains by measures of mass and cell number."
Hi, @futurebird! What do you think of the cutest flatmates I ever had? They are around 1.5mm long and help me clean the kitchen every day... could you help in determining their species?
@futurebird Interesting - I found an alate in our kitchen, so captured it in a tube in the hope that it was a queen, using cotton-wool to separate it from a reservoir of water.
When I came back a few days later I was initially surprised and dismayed to see that fungus had already formed - but then realised it was actually just cotton-wool. The ant had separated bits of cotton-wool from the main clump to surround itself. I like my chances of this being a fertilised queen.
In North #Cameroon, in the Mandaras Mountains, the #Mofu live a unique relationship with #insects, sharing with their homes & cultivations. A drought hit the region & #termites, usually a precious ally to the Mofu, have left the fields & invaded the huts and granaries.
To fight back, the Mofu people call for #Jaglavak. This ferocious army ant has the body of a dragon can chase termites out of the village.
