  Cerambycidae

spacer
Pronunciation: cer-am-BIS-si-dee
Common name: longhorned beetles

Identifying characteristics for the family Cerambycidae include:

  • Long filiform antennae, ranging from one-half to over two times the length of the body.
  • Body usually elongate and cylindrical; 2- to 60-mm in length.
  • Eyes generally notched with antenna arising within the notch.
  • Tarsi apparently 4-4-4, really 5-5-5 with the 4th segment small and inconspicuous.

Additional information:

  • The Chrysomelidae have the same tarsal formula as the Cerambycidae, but their antennae are shorter, the body is likely to be oval, and the eyes are not notched.
  • There are over 290 genera and 1100 species of Cerambycidae in North America, making it the seventh largest family of beetles.
  • Many species are brightly colored, making this a favorite group of beetle collectors.
  • Adults of many species feed on flowers, others feed on leaves and bark.
  • Larvae of many species are the roundheaded borers found in the wood of living, dying, and dead trees (cf. flatheaded borers of the Buprestidae).
  • The Cerambycidae play an important role in nutrient recycling in forest ecosystems. This feature, however, makes then serious pests in timber and wood products.
