Trinophylum cribratum Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Callidiopini > Genus Trinophylum Diagnostic Features of Larvae Mature larva. From the single larva at hand, which may possibly prove to be of this species, the characters are typical of those of the Callidiini, and its resemblance to that of Phymatodes testaceus (with which it bad been found).appears to be very close and differs as follows. Head subrectangular. Ocellus with distinct but feebly convex lens; pigmented spot less distinct. Mouthframe finely rugose, not interrupted beneath antenna. Antenna with second segment at least twice as long as broad. Maxilla with third segment of palp scarcely or not longer than second. Abdomen with ampullae much more coarsely reticulate. Pleural discs indistinct. Adapted from Duffy (1953). Biology and Economic Importance Biology unknown for members of this tribe. Species of this tribe are potentially invasive outside their native range. Selected References to Larvae Specimens Duffy, 1953
