It lives in old trees or decaying wood. Xylomyia is a genus of yellow and black, rather Ichneumon-like flies, with considerable outward resemblance to Xylophagus (LEPTiDiE), but the closed 4th posterior cell will easily distinguish them. The species seem to be much rarer in the adult than in the larval stage. Solva, Walker, antedates Xylomyia by one year, but as the subfamily name is constructed from the latter it should be retained.
