Zur Entwicklung,Färbung und Lebensweise vonPedostrangalia revestita (L.) (Coleopt., Cerambycidae)

Observations are given on phaenology and bionomy ofP. revestita in South Tyrol last years. The larvae develop exclusively within dead stumps of branches near the living tissue. The first attack shows secondary character but later the feeding can become primary. The time of flight occurred mainly in the middle of May. The quota of females amounted to 50% in the laboratory but only to 14% in the field. Apparently the males show more activity of flight than the females. The beetles swarm in the crowns of host trees about noon.
