Last week, I used a blacklight at night to catch some moths. I froze the small moths and fed them to my Camponotus floridanus. They enjoyed them very much, and it was actually the colony's first time eating protein (there are only four workers). So, I ordered a Drosophila hydei fruit fly culture because I figured they would love fruit flies since they loved the moths so much.

 

Well, I put the dead fruit flies in the outworld just as I did with the moths, but the workers would smell the fruit fly and then go crazy, running back to the nest and causing the other workers and queen to go crazy also. Basically every time a worker would approach a fly, it would jerk away and act as if the fruit fly is a threat. This did not happen at all with the moths I fed to them.

 

Why is this happening? How is a dead fruit fly a scary threat that they want to avoid, but a moth isn't? The whole purpose I bought these fruit flies was because of this picky colony.

That's funny. Maybe not in a good way, but I have seen this behavior so the visuals of them in full panic mode makes me laugh.

 

Have you tried giving it to them live? They will eventually come around to the scent. How long have you have them in the outworld?

When I tried to feed Drosophila hydei from a pet shop (gently pushed the fruit fly into the tube) to my Camponotus barbaricus they examined them very septically for a few minutes then grabbed them, carried all of them out and dumped them in the outworld. I think it has something to with the cups/boxes in which the fruit flies are held because they ate "wild" fruit flies (had some Drosophila melanogaster in my kitchen at that time) without issues.

 

I've read quite a few times by now that Camponotus do not like fruit flies. They seem to prefer crickets, meal/superworms, flies/maggots/pupae, and spiders (mine LOVE spiders).

We should respect all forms of consciousness. The body is just a vessel, a mere hull.

I had a similar situation with my Tapinoma sessile. They'll gladly take a dead spider, but one time I tried to give them a dead cricket and the whole bunch of them seemed to go nuts.

Yeah, my Camponotus love spiders as well.

 

Make sure the live fruit flies from the pet store have not been sprinkled with calcium powder. They do that as a nutrient for reptiles.

Be careful with spiders though. I fed my C. pennsylvanicus colony one last weekend and two (of the five) workers died within two days. 

 

On the other hand, the colony loves Drosophila melanogaster I froze em down and fed them about a dozen, they carry the flies into the nest and eat em up.

After coming home today and checking on this colony, they took 16 flies into the nest and have been eating. I guess they just needed to get used to them  :lol:

i find that my smaller Camponotus colonies love them. However my large colony dosent.

They're probably frying bigger fish.

This same thing happened to me with my own C. floridanus. I had given them some fruit flies a few months ago (they had about 40 workers then) that were pre-killed and they wouldn't eat, instead going back into the nest and retreating. Like you said, they eventually got used to them. When introducing a new food, don't get too worried as they may go crazy temporarily until they are comfortable with it. 😀

I gave a fruit fly to my Ochetellus. They tore off its wings and dragged it to the corner of the test tube (fruit fly is still alive). They then left it there. An hour later they ate it.

Also, my Pseudomyrmex are afraid of anything that moves. They only eat dead termites.
