Оxyporus (Oxyporus) vittatus Gravenhorst, 1802

Published data. LESCHEN & ALLEN (1988):description of E, L3, P, biology and hosts; HANLEY & GOODRICH (1994): notes on L3 morphology, fungal hosts; CAMPBELL (1969): distribution.

Larval morphology. Head and body sclerites without pigmentation, long non-articulated spines on mala, prementum with lateral setae 1/2 length of medial setae ( LESCHEN & ALLEN 1988). The earlier claimed absence of sublateral setae was rejected by observations in HANLEY & GOODRICH (1994). Characters to distinguish this species from O. stygicus are as follows: El1 located medial to uppermost ocelli; head seta L4 absent; 4 A and 4 P setae on pronotum; 7 A and 5 P setae on mesonotum; 4 A and 4 P setae on metanotum; no anterior setae on abdominal tergum I.

Development. Egg: 6 hours; instar I: 16.5 hours; instar II: 1.17 days; instar III: 5.86 days; prepupae: 3.6 days; pupae: 5.75 days. Total development duration: 17 days.

Behavior. Adults have been collected from April to October with the highest abundance during September and October. Preoral digestion of larvae was observed ( LESCHEN & ALLEN 1988).
