The unmistakable antennae on these amorous insects mark them as psilid flies, and commentator Chris Grinter (of The Skeptical Moth) correctly surmised the species as Loxocera cylindrica. Nine points to Chris, and one to FormicidaeFantasy who was the first to pick the order.
This brings us to the end of June and to the announcement of the overall mystery points winner for the month:
Ted MacRae, of the excellent entomology blog Beetles in the Bush, has accumulated ten points and is entitled to either a guest blog post here on Myrmecos, or to an 8×10 print from my galleries. Drop me a line and we’ll get you hooked up, Ted.
