A >>> Stephen Shaw <srshaw@DAL.CA> 2/16/2010 12:22 pm >>> Has anyone into winter hiking come across these, snow fleas (Mecoptera = scorpionflies)? They are expected to be black or brown, about 3 mm long, flightless (vestigial wings), come out on to the snow surface in the day in winter, and can jump. They have been photo'd from early December through mid February on Bugguide.net, in places like New Hampshire and Ontario. The species featured on Bugguide are mostly Boreus brumalis and Boreus nivoriundus. A colleague from Cambridge, Malcolm Burrows, who visited here a couple of years ago to work on jumping mecahnisms in true bugs, is coming back again later this year. He is the expert on the mechanics of insect jumps and has just asked me if any species of Boreus is found here. Has anyone seen any jumping critter like this somewhere in N.S., and if so at what sort of date? Thanks, Steve
