Beetle? - Tasgius ater
Logy Bay, Northeast Avalon, Newfoundland/Labrador, Canada
July 16, 2006
Size: 9mm Body Length
We found this on the carpet in our basement about 11:00 PM. It did not seem healthy; close to dying actually. It kept falling over and landing on its back. Can anyone ID it?

Very susceptible to moisture loss.
For such ferocious little critters this beetle family has a huge Achilles' heel: Deprive them of moisture and they soon curl up and die, which is probably what's wrong with this one.

Thanks
Very interesting. I'll bet that's exactly the problem. Thanks for explaining this.

Staphylinidae: Staphylininae: Staphylinina
subtribe Staphylinina. At 9 mm it is too small to be a Tasgius, which is what it looks like.

Thanks!
Thanks! I don't see any guide page for the Subtribe Staphylinina under Staphylininae, so I'm moving these images to the Staphylininae page.

Rove Beetle.
This is a fairly large rove beetle, family Staphylinidae. Don Chandler may be able to be more specific. The shortened elytra (wing covers) are characteristic of staphylinids, which are predatory insects.
