Chlorophorus annularis
Classification
Diagnostic Features of Larvae
- Mature larva. Rather similar to that of Clytus arietis, from which it may be distinguished as follows. Form more slender; length up to 23 mm; maximum breadth (at prothorax) 4 mm. Head with sclerotization of mouthframe interrupted beneath antenna. Hypostoma with front margin narrowly pale testaceous, with transverse rugae; sutures very pale testaceous. Antenna with third segment slightly tapering, three times as long as broad; supplementary process elongate, conical, nearly half as long as third. Maxillary palpi with third segment distinctly longer than second. Legs minute, shorter than third segment of maxillary palp.
Pupa. Similar to that of C. arietis, from which it differs by the absence of ferruginous tubercles on the pronotum and by the arrangement of the spines on the seventh abdominal tergite. Adapted from Duffy (1953).
Biology and Economic Importance
- Members of this tribe are known from various host plant families and several genera (e.g., Chlorophorus, Xylotrechus) are considered economically important. Species of this tribe are potentially invasive outside their native range. More information is available at the CAPS website.
