Eucnemid pupae! - Dirrhagofarsus ernae

Eucnemid pupae! - Dirrhagofarsus ernae
Nashua, Hillsborough County, New Hampshire, USA
January 10, 2007
Size: 6 - 8 mm
Many of the eucnemid larvae I collected on January 10, 2007 have pupated, probably due to having been brought into a warm house. Shown here is a live pupa and the posterior of a dead one. With luck we will have adults in a week or two and the larva-based ID can be confirmed.

raising pupae
Dear Jim,

this often ends up in failures, if pupae are not within their chambers they need for proper hatching. If you store them in paper rolls of appropriate diameter (quickly done, but don´t use forceps to put them in), most will hatch perfectly, though!

best wishes!

 
True
Pupae are rather fragile but I have reared many to adulthood. At present these are loose in a sealed container with plenty of small, moist scraps of their white-rot aspen wood. There are certainly more of them pupating inside the larger-sized chunks of wood in the same container, so even if all the loose ones died I should still get some adults for final ID confirmation and photos.

Tom Murray has also had good success rearing larvae during the past year and we are steadily building a database of beetle lifecycle documentation.
