scientific name    Laphria janus    

habitat
Open glades within boreal, transitional, and Cordilleran forests. Frequently found in dry spruce forests and often in adjacent grasslands (Cannings 1994, 1997).

seasonality
Adults are found late may through July, and possibly earlier in the southern portion of the range.

identification
Medium to large, 10-20 mm in length. Laphria janus is a conspicuous bee-mimic which is generally robust, with highly-pubescent raptorial legs and an enlarged hypopharynx used in hunting. The hypopharynx of this species is surrounded by coarse white to yellow setae, referred to as a mystax. Antennae are stout and short, and eyes are large and conspicuous. Moderately course hairs (pubescence) are present and cover the posterior ends of the thorax and abdomen; L. janus is easily distinguished from other Laphria by the abdominal piles being orange and thoracic piles being yellowish. Fine pubescence can continue along the whole of the thorax and abdomen. Males have a slender abdomen, while females have a more rounded abdomen. (McAtee 1919; Adisoemarto 1967).
