Larvae of Placusa despecta Erichson collected in association with adults were described in detail and compared with reared larvae of Placusa tachyporoides Waltl. Illustrations of structural features and chaetotaxy are provided. These larvae are very similar to those of Euvira Sharp. These similarities are outlined and a table of features which will distinguish between larvae of these two genera is provided. Gut contents of both larvae and adults were composed of large masses of hyphae, asexual fruiting structures and similar parts of imperfect fungi. This, as well as structural evidence, strongly supports the conclusion that both adults and larvae of Placusa are primarily fungivores in the subcortical habitat.
