Оxyporus (Pseudoxyporus) occipitalis Fauvel, 1864

Published data. LESCHEN & ALLEN (1988): morphological description of E, L3 without chaetotaxy, P; HANLEY & GOODRICH (1993): hosts and distribution.

Larval morphology. Head and body sclerites without pigmentation; prementum with lateral setae 1/4 times as long as medial setae, sublateral setae absent; from two to three articulated spines on the inner lobe of mala.

Development. According to LESCHEN & ALLEN (1988), the third instar larvae left the fungal fruit body four days after collection and afterwards developed into adults in five days. HANLEY & GOODRICH (1993) showed that full development in laboratory at room temperature from egg to imago is very short and takes only 17 days as follows: egg: several hours; instar I: approximately one day; instar II: appr. one day; instar III: appr. six days; pupa: appr. six days.

Behavior. Females were typically laying eggs in the chamber built inside the gill layer of the fungi ( LESCHEN & ALLEN 1988). According to HANLEY & GOODRICH (1993), O. occipitalis were collected only from the mature fungal fruit bodies. A male and female were once seen copulating on a host fungal cap. Hatching was said to begin several hours after collecting the eggs. In the Pacific Northwest ( USA) this species was collected mostly in October, but overall across its range from September to November.
