|scientific name Brachys aerosus |
This species is easy to recognize on the shape of the body, small size and colour pattern.
In the river valley below the U of Alberta in Edmonton, there is one Saskatoon berry bush, about 1 meter high, that for several years running has hosted a population of B. aerosus adults. The leaves of this bush are heavily mined by the end of summer. Neighbouring bushes appear unaffected.
These beetles are reported to feed on a wide variety of hardwoods, including aspen, maple, and elm (Bright, 1987). In Alberta they have been associated with aspen, poplar, and Saskatoon berry.
In Canada the beetles are found from Alberta to Nova Scotia, and south in the United States to Arizona and Texas (Bright, 1987).
