Oeme costata Classification Family Cerambycidae > Subfamily Cerambycinae > Tribe Oemini > Genus Oeme Diagnostic Features of Larvae Larva. Distinguishable from Oeme rigida only by the coarser and more densely set hairs, often chitinous tarsus, usually white ocellus, and transversely oval labrum. Pupa: The pupa is characterized by almost total absence of spines on the body. The tergum of the mesothorax has a small group of spines near the posterior median margin, and a transverse band of from six to eight small spines occur on the first three dorsal abdominal segments. The larval habits are similar to those of O. rigida. It is more commonly found in branches. Adapted from Craighead (1923). Biology and Economic Importance Biology unknown for members of this tribe.
