water penny beetle - Psephenus herricki
Fall Creek, Ithaca, Tompkins County, New York, USA
July 15, 2007
Size: 6mm
About 8-10 of these were sitting on a mostly submerged rock in the creek.

I've been rearing a couple
since July '08.

I assume you mean larvae? Interesting -- that's rather different from rearing beetles in wood or fungus; it sounds more difficult. You'll have to let BugGuiders know if you succeed in getting adults. Only another half year to go.

Yes, I collected several larvae and two survived
so far. I have them in a clear plastic container with water and rocks and an aerator hose bubbling away. I keep it in a window so it gets enough light to grow algae on the rocks. That's what these guys eat. I collected an Ect*opria too but it died.

quite an undertaking maintaining the right environment for a whole year, but it sounds as if you're doing well with it. I wonder if anyone has ever tried to rear these before.
