Typocerus velutinus Classification Family Cerambycidae > Subfamily Lepturinae > Tribe Lepturini > Genus Typocerus Diagnostic Features of Larvae Larva. Form elongate, subcylindrical, tapering; integument smooth, shining, very sparsly clothed with whitish yellow hairs. Head sub-orbicular, slightly wider than long, somewhat chitinized; mouth-frame strongly corneous; epistoma slightly and roundly protuberant, three or four setae on each side; clypeus and labrum thin, latter semicircular, one and one-half times wider than long, widest behind, bearing scattered hairs; mandible slender from side, apex acute, dorsal angle prominent; antennae small, very retractile, ring oval; ocellus indistinct; anterior edge of hypostoma distinct; hypostoma broadly curved; gula not distinct, palpi slender, last joint of maxillary obtusely conical, shorter than last labial or second maxillary; lacinia cylindrical. Prothorax one-half wider than long, pronotum bearing a distinct transverse brownish band, widened at sides, posterior area slightly rugulose, shining. Eusternum velvety pubescent, dull, except for a triangular anterior spot; mesonotum dull, velvety pubescent, as well as metanotum, except for a central group of shining tubercles; mesosternum and metasternum tuberculate. Legs not so slender, no joint twice as long as thick; tarsus attenuate, chitinous.

Spiracles very small, oval to sub-orbicular, peritreme thin. Adapted from Craighead (1923). Biology and Economic Importance One of the commonest lepturiform larvae, found in all sorts of decaying hardwoods and conifers, occasionally in rather solid wood. The adults are commonly found on flowers in May and June throughout the eastern US and Canada. Adapted from Craighead (1923). Selected References to Larvae Specimens Craighead, 1923
