Dytiscus - Dytiscus hybridus - Male
Plymouth, Wayne County, Michigan, USA
March 18, 2011
Size: est 1 inch
Found in parking lot near wetlands.

D. hybridus
Based on coloration of the legs and pronotum.

Moved from ID Request.

Predacious diving beetle
Should be in Genus Dytiscus....

Thanks for that! Convinced it's Dytiscus marginicollis now. Found more info at

marginicollis very unlikely
8 Dytiscus spp. listed for your state, but D. marginicollis is not among them(1)

Oops, yeah, seems to be a lot of Dytiscinae that look similar. Could be hybridus or harrisii... good lesson for me to take a ventral photo next time.

happy end
turns out, your shots provided enough detail for a positive ID.
nice; pls keep posting your bug pix on BG, Grandpa ))
