Syneta Dejean 1835
8 spp. in NA(1)
6-8 mm(2)(3)
Small, elongated, almost cylindrical; resemble some longhorns. Characters (2):
antennae less than half as long as body
body with scattered, fine hairs
elytra wider at base than pronotum
sides of pronotum dentate (toothed)
mostly northern (NF-AK, south to montane NC in the east and CO-CA in the west)(1)
on trees(1)
Adults are associated mostly with conifers of the Pinaceae family (larch, pine, spruce, fir, etc.), but S. ferruginea (an eastern sp.) prefers Betulaceae (alder, birch, hazel, etc.), and the western S. albida attacks various deciduous trees, incl. fruit trees(1)
Life Cycle
S. albida larvae feed on tree roots, hibernate in soil, and pupate in spring(3)
