Classification
Diagnostic Features of Larvae
- Larva. Form contracted, subcylindrical; integument firm, shining, clothed with fine yellowish-red hairs. Mouth-frame greenish-yellow; labrum roundly oval, slightly wider than long; mandibles short, robust, basal piece reddish, about one-half length of distal, latter having no foveae; first antennal joint transverse, second longest, third shortest; ocellus distinct, contiguous with base of antennae; gena neither shouldered nor setose. Ventral mouth-parts fleshy; joints of maxillary palpi subequal, basal transverse, second about as long as wide; process of palpifer about equal to last maxillary joint; gula distinct; anterior portion of hypostomal plates swollen and wrinkled. Prothorax having four distinct tergal plates, alar and lateral areas sparsely haired; pronotum posteriorly shining and irregularly wrinkled; eusternal spots glabrous, shining. Mesonotum and metanotum dull, finely granulate. Legs absent. Ampullae faintly shining, finely granulate, having only lateral impressions; pleural discs indistinct; abdominal spiracles broadly oval to suborbicular, a little larger than the ocellus, peritreme thin. Pupa: Short, erect, chitinous points on anterior margin and perimeter of pronotum; irregularly dispersed over abdominal terga, becoming larger and more numerous posteriorly and forming a row on hind margin of the seventh and eighth, these points recurved. Adapted from Craighead (1923).
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.
