Birandra silvaini Classification Family Cerambycidae > Subfamily Parandrinae > Tribe Parandrini > Genus Birandra Diagnostic Features of Larvae Mature larva. Similar to that of Parandra glabra but distinguishable as follows: Prothorax with pronotum finely asperate and testaceous posteriorly. Asperities of metasternum testaceous, Jess strongly transverse and about equal in size to those on abdominal segment 1. Size smaller. Length up to 32 mm; maximum breadth (at prothorax) 6 mm. Pupa. Similar to that of P. glabra but separable by the much more robust and longer urogomphi. Length up to 19 mm; maximum breadth 5.1 mm. Adapted from Duffy (1960). Biology and Economic Importance Larvae of most species develop for about one year in rotten wood. No species are known to attack living trees or firewood, so they have no adverse economic impact. Adults are relatively short lived, probably most living less than several months. Adults feed little, or not at all (summarized from Linsley, 1961; Lawrence, 2007, and other sources).
