Status
This impressive species is among the largest robber flies in North America by weight, although large, elongate asilid species may exceed its body length of 23-35 mm (Bromley 1934). Laphria grossa flies with a very audible loud buzz, and resembles a queen bumblebee in flight. It tends to frequent hardwood forest, and males often take up perches on vegetation adjacent to a large log or stump, especially oak or elm. Like most Laphria, L. grossa is active as an adult primarily in early to mid-summer.
