Camponotus Pennsylvanicus Pupae cases are almost black...
Basically, as stated in the title.
I have some pupa who should be eclosing any day now. Some of the cases are starting to turn black.
Now, I know pupa cases are supposed to darken before eclosing, but I've never seen anything this drastic in my formica ants.
Could it be dead somehow?
What does a dead C. Pennsylavnicus pupa's case look like?

Mine get pretty dark before enclosing. I have C. Pennslyvanicus. I think it depends on the colour of the ants. Ie brown ants will have lighter cocoons.
Keeper of:
Camponotus Pennsylvanicus
Temnothorax ambiguus/curvispinosus (Acorn ant)
Lasius Interjectus (Larger citronella ant) with host workers: L. Americanus

There are black ants in there, so naturally, the pupae will turn very dark! Nothing to worry about! If they were dead, the queen would eat them!JDSweetMeat wrote: ↑Wed Jul 31, 2019 10:43 pmBasically, as stated in the title.

Re: Camponotus Pennsylvanicus Pupae cases are almost black...
if the queen hasn't eaten it or thrown it in the trash then chances are its still alive, when i brood boosted my lasius niger all the pupa that didn't make it got put in the trash pile
1x Lasius Niger - early forging stage - 60-100 workers
1x Messor Barbarus - founding stage - <20 workers
1x Camponotus Turkestanus - claustral stage - 1 nanitic + brood
1x Odontoponera Transversa - semi-claustral stage - no eggs

Re: Camponotus Pennsylvanicus Pupae cases are almost black...
The eclosed ants are paralyzed -- I had one that the C. Penn took out of its cocoon -- they kept it for a week before they took it away from the main cluster of pupae (and it started decaying). About 1/4 of the pupae developed like those (essentially they were paralyzed).

That doesn't sound plausible to me. I'd suspect an environmental influence.SYUTEO wrote: ↑Fri Nov 15, 2019 1:35 amPerhaps they were molting?JDSweetMeat wrote: ↑Fri Nov 08, 2019 8:49 amThe eclosed ants are paralyzed -- I had one that the C.
