Gaurotes cyanipennis Classification Family Cerambycidae > Subfamily Lepturinae > Tribe Rhagiini > Genus Gaurotes Diagnostic Features of Larvae Larva. Form strongly depressed, subparallel; integument smooth, shining, sparsely clothed with very long, castaneous, attenuate hairs. Head very depressed, transversely oval, widest at middle, strongly coriaceous and beset with numerous slender setae; epistoma very thin, straight, fused with clypeus at middle; clypeus and labrum thin, latter twice as wide as long, anterior margin rounded, ciliate; front transversely divided; mandible very slender from side, more than twice as long as wide at base, tip dilated slightly, cutting edge short, truncate; antennae very small, retractile; ocelli two, often indistinct. Anterior edge of hypostoma thin, straight; mentum transverse; palpi very slender; last maxillary joint acute, as long as second; last labial acutely conical shorter than basal; lacinia cylindrical; gula not evident, a single suture. Prothorax twice as wide as long; pronotum undifferentiated, smooth, shining. Eusternum smooth, broadly rounded in front; mesonotum and metanotum velvety asperate, only metasternum tuberculate. Legs slender, femur and tibia subequal, tarsus attenuate, curved. Abdomen much depressed; dorsal ampullae bearing four rows of small, prominent, contiguous tubercles; the ventral ampullae, two rows; pleural tubercle oblong, oval, bearing five setae, ninth tergum fringed with numerous long setae. Spiracles orbicular, prominent, peritreme wide, chitinous. Adapted from Craighead (1923). Pupa. Front of head around base of antennae beset with a few strong hairs and a group above eyes; anterior, posterior, and lateral margins of pronotum bearing a single row of closely set, long hairs, row on posterior margin forming an angle; mesonotum glabrous; metanotum bearing two patches of long hairs and each abdominal tergum also bearing a transverse row, broken in middle, of finer hairs; last tergum bearing a short, straight, acute spine. This species feeds between the bark and wood of dead walnut (Juglans) in a manner similar to that of Rhagium. It has also been found in Quercus, Prunus, Rhus, Nyssa, and Cornus.
