Classification
Diagnostic Features of Larvae
- Larva. Form elongate, strongly depressed; integument firm, covered with short, rather stiff hairs. Head very strongly depressed, sides regularly and strongly converging posteriorly; epistoma straight; labrum a little wider than long, broadly rounded, widest near base; mandible slender, elongate, length about three times condylar width, cutting-edge shallowly emarginate, antennal ring faintly bisected by frontal suture. Ventral mouth-parts elongate; mentum twice as wide as long, distinct; last joint of maxillary palpus shorter than penultimate, much shorter than last labial; anterior edge of hypostoma straight; gula not distinct. Prothorax depressed; pronotum posteriorly beset with chitinous, conical papillae, as also are the ampullae; pleural tubercles broadly oval, having a chitinous pit at each extremity and five or six setae; spiracles broadly oval, peritreme thin. Adapted from Craighead (1923).
Biology and Economic Importance
- Acrocinus longimanus is commonly collected at lights and on dead or dying trees, especially strangler fig (Ficus spp.). This species is known from a variety of host plant families, including the economically important families Fabaceae and Sterculiaceae.
