Pyralidae, Pyralinae - Hypsopygia mauritialis

19/7/2007

Strange-looking moth emerged from an observation colony of Polistes olivaceus this morning, and I suspect it is parasitic on this species.

Thanks in advance

Hypsopygia mauritialis.

Pyralidae, Pyralinae.

Don't know if this is a detritivore (feeding on the nest and/or dead wasps) or a predator (feeding on the eggs or larvae of the wasp), but I'd suspect a detritivore role, which would be in keeping with other members of this subfamily.

This moth is quite common, so likely to be found from nests of other colonial wasp species.

cheers,

Roger.

Thanks for the info!
Not sure if this has anything related, but the pupal caps of the affected colonies took on a very weird appearance, after which these moths emerged from those cells instead of wasps. Will try to take some photos later.

A bit late, but I finally found the photo I took of the parasitized nest. The cells in question have quite a weird appearance, different from the usual cocoon caps of wasp pupae, and I'm guessing that those are the cocoons of the moth pupae instead. The infestation seems pretty bad on some nests, and I noticed that on nests with large-scale infestation, the wasps are much less defensive and tend to flee the nest when disturbed instead of attacking.

There appears to be a complex of species based around Hypsopygia mauritialis. I'll need to do some dis-sectinig to sort out if they're all the same or not.

cheers,  Roger.
