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
