Friday Beetle Blogging: Nemognatha Blister Beetles


Nemognatha Blister Beetle, California.

Some of the oddest blister beetles in western North America are in the genus Nemognatha.  Their mouthparts have become elongate to form a proboscis- a common trait among other groups of insects- but rare among the beetles.  They are commonly seen on flowers feeding on nectar.

A proboscis? As in soldier beetles, or even more developed than this?

Didn't see any ICBB's on your blog.

I lived next to the park for almost a year and spent time unscientifically watching the various creatures there. Spent a fair bit of time looking at ants, there were several ant superhighways on my lane next to Jeremy Wash. I'm no scientist, just enjoyed watching their apparently purposeful movement and co-operative positioning.
