As mentioned in an earlier post New Fly for North Campus, we've been trapping insects on the North Campus for a while now. This week however, is a milestone for NHM as we held our first quarterly insect survey. Our aim was to go after the insects that our Malaise trap wasn't sampling, like large flying insects such as crane flies and bumble bees and ground dwelling insects like earwigs and beetles. Since this was our first time and the site is still an active construction zone, we limited participation to NHM staff and partners. As the specimens get prepared and sorted, I'll keep you all up to date on the species we identify.

Look closely, I swear there's an insect there!
A common insect, but nonetheless an impressive catch.

Insect Trapping To better understand the insect diversity of the North Campus, we've started surveying the insect fauna on the construction site. A few months ago, Dr. Brian Brown, the Museum's Curator of Entomology, set up a Malaise trap. This type of trap is commonly used by entomologists to capture small flying insects, and so far we've collected hundreds! One of the coolest (at least in Brian's opinion, and now mine too) is the Boatman Fly.

It was first recorded in California in 1963, and to date has not been recorded in any other state. These flies are quite striking in appearance with their brightly colored eyes and highly patterned wings. Males of the species are often seen walking over leaves waving their wings in display, which look very much like a person rowing a boat, hence the name.
