Batocera rufomaculata
Classification
Diagnostic Features of Larvae
- Mature larva. Head elongate, rather strongly depressed, widest at anterior third and strongly converging posteriorly. Frontal sutures indistinct; antennal foramen closed behind; mouthframe extremely strongly and very broadly sclerotized, pitchy; frons pitchy anteriorly and with numerous setiferous pores; six epistomal setae present. One pair of ocelli present; lens round, feebly convex, pale, sharply contrasting with surrounding sclerotized cuticle; pigmented spot indistinct. Hypostoma fiat, ferruginous, with a few transverse rugae; sutures distinct, curved; gular region undefined. Clypeus bearing a few lateral setae. Labrum transversely oval, bearing coarse setae. Antennae 3-segmented; basal membrane long, fleshy; segment 2 about twice as long as basal width; segment 3 small but distinct, slightly elongate and bearing a few apical setae; supplementary process about half length of segment 3. Maxilla with segment 3 of palp conical, much shorter than segment 2. Labial pal pi with segment 2 much shorter than segment 1. Mentum distinct from submentum. Prothorax with pronotum ferruginous and smooth except for front margin, which is narrowly testaceous, with a transverse fringe of short, dense setae; posterior two-thirds extremely coarsely asperate, the asperities transverse and larger towards lateral grooves; postnotal fold well developed, bearing about five transverse rows of elongate, subcylindrical, subvertical asperities; anterior row of asperities distinctly larger than those on remaining rows, which become gradually smaller posteriorly. Miller (1926) records the maximum length of this larva to be 100 mm. Adapted from Duffy (1960).
Biology and Economic Importance
- Members of this tribe are commonly intercepted at ports of entry around the world. Species of this tribe are potentially invasive outside their native range.
