Bug ID - Cybister

Bug ID - Cybister
Louisiana, USA
September 4, 2008
This crawled up on the front porch during the night, getting away from all the rain.

Moved from Cybister.

Moved from Dytiscus.

Moved from Dysticinae.

Cybister I believe...


would probably help with the ID.

size matters
Yes, but unfortunately I don't have that info. I'm asking this ID for someone else, and they can't provide the info either.....

Quite similar to Water tigers of Diving beetles, I don't think they come out of water like Adults.

They do to pupate.
I suspect this specimen was looking for a place to dig in and pupate. There must be some standing water somewhere really close, though.
