Lasioglossum lineatulum, female, back
Lasioglossum lineatulum is defined in my mind by having relatively few pits on its scutum, a shinyish abdomen, and long straitions on the propodeal triangle. Otherwise it looks similar to the 100 plus other species in the group. This one was captured on Sleeping Bear Dunes National Lakeshore in Michigan. Pictures taken by Sierra Williams, photoshopping by Elizabeth Garcia. Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200. USGSBIML Photoshopping Technique: Note that we now have added using the burn tool at 50% opacity set to shadows to clean up the halos that bleed into the black background from "hot" color sections of the picture.
