Phymatodes aereus Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Callidiini > Genus Phymatodes Diagnostic Features of Larvae Larva. Form subcylindrical, slightly depressed; integument firm, smooth, not very shining, densely covered with lemon-yellow hair. Head subtrapezoidal, gradually widening behind antennae: mouth-frame corneous, castaneous to dirty black; labrum fleshy, transversely oval: mandibles about as long as wide at base, basal piece brown, narrow, one-third width of distal, tatter piceous, shining, median impression on outer face; antennal joints slender, second joint Longest, supplementary slender, distinct; ocelli none; gena receding not shouldered, no bristles; ventral mouth-parts scarcely coriaceous; lobe of palpifer distinct; ultimate joint of maxillary palpi twice length of penultimate, equal to last labial; subfossal spine absent ; gular sutures parallel. Prothorax roundly rectangular; pronotum one and one-half times as wide as long, hairy on anterior half, posteriorly very finely and regularly striate, merging into finely granulate, median impressions faint, pronotal and proalar plates distinct, ochraceous; sternum undifferentiated, hairy, having a dull granulate band in center, bordered by two glabrous shining spots. Mesonotum and metanotum dull, finely granulate. Legs small, four-jointed, about equal to maxillary palpi. Abdomen: Segments wider ventrally, ampullae with no definite transverse impressions, dull, finely granulate. Pleural discs distinct on first, second, and third abdominal segments. Spiracles narrowly oval, peritreme thin. Pupa: Form similar to that of adult, pronotum bearing a small obtuse tubercle on anterior margin, unarmed except for an irregular row of a few tiny, short, acute, chitinous points on posterior margin of second to last abdominal terga. Adapted from Craighead (1923). Biology and Economic Importance Members of this tribe are known from various host plant families and several species are considered economically important. Species of this tribe are potentially invasive outside their native range. Selected References to Larvae Specimens Craighead, 1923
