Fig Beetle

Cotinis mutabilis

Description:

Cotinis mutabilis, also known as the "green fruit beetle" or "fig beetle" and also as "junebug", is a member of the scarab beetle family. It belongs to the subfamily Cetoniinae, comprising a group of beetles commonly called flower chafers since many of them feed on pollen, nectar, or petals. Its habitat is primarily the southwestern United States and Mexico. Figeater beetles are often mistaken for green June beetles (Cotinis nitida) and Japanese beetles (Popillia japonica); however, they do not damage lawns and fruit crops to the same extent as their eastern cousins. Adult figeater beetles grow to approximately 1.25 inches (3 cm). They are a dull green on the top and a brilliant iridescent green on the underside and legs. They are active during daylight hours, often congregating in the shade of trees near choice breeding grounds to find mates. They make a loud buzzing sound similar to that of carpenter bees.

Habitat:

I found these poor guys dead and headless in my compost bin. I also routinely find their larva at the bottom of the compost bin. I leave them alone because I'm sure they're doing some of the work of composting my kitchen waste.

Notes:

When alive and flying around, these big beetles are clumsy and often seem to be trying to land in your hair.

Thanks Ashish -- couldn't have gotten that view except they were dead.

m-m and n-p: I love your description of Austria (mountains not kangaroos). I guess people make that mistake a lot. At least one of my spottings is from Austria (crested lark) as I go there for part of my vacation every few years.
