Unknown Beetle - Macrosiagon pectinata - Female
Montrose, Laurens County, Georgia, USA
May 25, 2010
I originally thought for sure this was a Casebearer, but the wings overhang the rear and are too elongated. Found on wild raspberry/strawberry. Note that I have subsequently found another type that has red on the dorsal thorax/pronotum rather than the abdomen. Does this signify male/female coloring or different species, perhaps?

Macrosiagon pectinata
This is another tough one- it appears to be a non-standard color variant of M. pectinata, which is hardly saying anything. Macrosiagon pectinata is the name given to almost anything that isn't immediately recognizable as something else...

cheers,

Ripihoridae
Nice shot of a wedge shaped beetle. They lay their eggs in bee's nests.

Thank you, Beatriz....
I can see why these guys are rarish around here. I haven't seen a single bee nest/hive in this area although there are a number of the small species flying around, no common honey bees, though.

Native bees
I don't think that they are interested in honey bees; it is the ground nesting, solitary, native bees that they go for.

Actually, it's the genus Ripi
Actually, it's the genus Ripiphorus that goes after bees (some are solitary, some are sub-social). Macrosiagon species go after solitary wasps (mud daubers and the like).

cheers,
zack
