Ant Crickets - Family Myrmecophilidae

I have always been fascinated by these little fellows. Up until Pi Day 2010 i never knew what they were, however. I didn't know if the little 2-3mm long fellows i was seeing were immature versions of larger crickets or if they were some kind of crazy pixie crickets.

I am going to take a stab at keeping the small number i collected today alive... but i want to make a serious effort to breed these. I am going to do research and put all the interesting info into this thread.

It is my hope that these could be a scabies feature feeder in the future =P

RATS! It seems these little crix might have to live along side an ant nest... and danged if i sort of recall being annoyed that there was some ants by them :/

this tiny cricket is exploring an oak leaf, to give some idea of the scale of these insects






TAXONOMY:
[2] says there are only four species in NA and it seems like we might be in range of two:
Myrmecophilus manni: western states rangemap --> http://entnemdept.ufl.edu/walker/buzz/391a.htm
M. oregonensis: west coast states and southwestern BC rangemap --> http://entnemdept.ufl.edu/walker/buzz/393a.htm

NATURAL HISTORY:


[note: i am still working and editting this... if you want to follow the thread and see the finished product develop you can check it out here: http://scabies.myfreeforum.org/about4615.html ]




right now i still have at least one little dude kicking around the jar i set up for him. he still is moving with vim and vigor and hides from my finger and what not. this sunday i am hopefully going to collect a Componotus (spell?) ant nest and more acrix :D

Very interesting little critters. If they can be bred in captivity they would make great feeders for little things like trues and bitty slings. I hope you're successful.

well, i would need at least 1000 (thousand) adults to make these feeders


mamma lays an egg about 1/3 as big as her body!

i suspect these are rather k selected breeders :/

Very interesting. If you get this going it'd be very interesting. So I wonder if they are obligative symbionts of ants(in captivity maybe not!)

What exactly is the benefit of the ant colony in their lives?

from stuff my buddies have researched and i have read it looks like it shakes down like this:


they are hard to get to do fully do their thing in captivity. in a lab, w/o ants they lived 3-4 months. with ants 4-5 months.

as for what the crix exact relationship to and benefit from the ants is not exactly clear to me yet. the crix sort of tend to or stroke or clean the ants i guess. they might eat the gleanings from their cleanings. ants make all kinds of goofy pheremones and chem trails and stuff... so that could actually be hideous complex stuff going on


a VERY interesting, though not directly observable, trait of the crix is their apparent ability to manipulate their own pheromones and chemicals to more closely match what the ants they live are expecting. it seems the crix can change host colonies and even host species and take about a week to retune themselves to their new ant providers. i am calling them "smell chameleons" =P


i have several plans right now for things i want to try with these little crickets. i am going to try to find a small ant nest (i need to research Camponotus carpenter ants, as they are a known host genus... and might be one of the easier ants to keep in captivity. it might be possible to find papers that explain exactly what the crickets need, as we have just began to scratch the surface, really. I am hoping to do university library runs at some point, so i should have increased access to any papers that aren't freely available.

Wow, those critters are even smaller than some fleas like the cat flea!

Sounds like too much trouble for feeders...

Very interesting stuff makes me think of the ant mimic spiders.

At last, I found another interesting thread. About a year ago or two, a fellow local keeper keeps on bugging me because he found a weird looking bug that looks like an Orthoptera, he said that it is a cohabitant of Paratrechina longicornis. I've also seen it in person, by that time we called it ant cow because a "herd" of it is being guided by the ants to a colony entrance. And the morphology seems to be the same, though we are here in the Philippines.

Could you buy a couple of ant farm kits, and introduce the crix to the ant farms, instead of using a hill? Also try to move the crix between the different ant farms to see the effect of the smell chameleonism?.:confused:
