Boreus elegans Carpenter
The Boreidae (from the Greek "Boreas" -- the North Wind, the North) or snow scorpionflies are small mecopterans that resemble minute grasshoppers. The Holarctic genus Boreus, the only one of the family in British Columbia, was chosen to represent the province for several reasons. British Columbia is a province of mountains and snow, the characteristic habitat of these insects. They are striking and distinctive, with interesting and unusual behaviour. Five of the seven known Canadian species live in the province.
Boreus elegans is the most distinctive of the British Columbia snow scorpionflies. It is considerably larger and redder in colour than the other four species of Boreus; as its name suggests, it is the most handsome of the genus. In Canada it occurs only in British Columbia. Although it is not distributed as widely in the province as some of the other species (B. californicus, B. pilosus), it inhabits the Coast Range and lives among the mountains by the sea, the two features most often associated with our province (and now linked with the image of Boreus on the ESBC seal).
Boreus adults are dark long-legged insects which appear in the fall and winter. They are often found hopping and walking on the surface of the snow, where they are conspicuous due to their movement and contrasting colour. The male has vestigial, bristle-like wings with which he grasps the female during mating. In the female, the wings are further reduced to small scales. The female has a long and conspicuous ovipositor.
The larvae are C-shaped grubs with a well-developed head capsule and three pairs of thoracic legs. They live at the base of the moss and clubmoss plants on which they apparently feed, although they probably also are saprophagous and carnivorous.
This is a slightly modified version of an article in the inaugural issue of Boreus (April 1981), written by the editor at the time, Rob Cannings.
At the ESBC Director's meeting on 27 November 1980, those present chose the genus Boreus (Mecoptera: Boreidae) to represent the Society on a new logo. Dr. Cannings was given the task of recommending a particular species of Boreus for this honour. His only instructions were: "Make sure you choose a good species…we don't want the Society's insect to end up as a forgotten synonym in a few years!" Boreus elegans Carpenter was the final choice.
