Neoplocaederus viridipennis Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Cerambycini > Genus Neoplocaederus Diagnostic Features of Larvae Mature larva. Rather similar to those of Cerambyx species, from which it may be distinguished as follows. Length up to 42 mm; breadth (at prothorax) 11 mm. Head with genae ferruginous, rugose; temples without carinae or raised areas. Dorsal boundary of antennal foramen not raised, scarcely produced, ferruginous. Front margin of frons with upper boundary less strongly marked, straight. Antenna longer; third segment about four times as long as basal width. Hypostoma transversely striate near front margin. Prothorax with front margin rather densely fringed with reddish setae. Abdomen with ampullae without tubercles, spiculate. Anal lobes rather densely setose. Spiracles with about nine distinct marginal chambers. In mature larvae the milky white calcium fluid is visible through the larval integument. Larvae which have already constructed their calcareous cocoons will have become reduced to about half their original length. Pupa. This pupa is very similar to those of Cerambyx species, from which it differs as follows. Head with antennae shorter, the segments slightly pectinate on outer margin. Labrum with a row of spinules across base. Mesonotum and metanotum with a few scattered spinu1es. Abdomen with tergites two to six with spines simple at base. Eighth tergite acutely produced posteriorly (as in Aromia); a few ferruginous spines present. Ninth tergite with a few scattered ferruginous spinules. Adapted from Duffy (1953). Biology and Economic Importance Members of this tribe are known from various host plant families. Species of this tribe are potentially invasive outside their native range.
