Оxyporus (Oxyporus) femoralis Gravenhorst, 1802

Published data. CAMPBELL (1969): biology; LESCHEN & ALLEN (1988): description of L1, L3, biology.

Larval morphology. Distinguished from other described Oxyporus larvae by the darkly pigmented head and sclerites; short and sublateral setae present on premental sclerite ( LESCHEN & ALLEN 1988: fig. 3G).

Development. Third instar larvae developed into adults in laboratory at room temperature in 10 days after their collection.

Adults and larvae have been collected in the north of United States (Michigan) from May to October and from July to November in the southeast (Arkansas). No beetles

were collected during a drought in Arkansas in July when fungi were scarce ( LESCHEN & ALLEN, 1988).
