Key for the Andrenosoma-species

back to the key to Laphriinae start of the key

Only two rare species are recorded from Germany. During the last 50 years a number of populations collapsed due probably to the exchange of wooden materials (e.g. for telephone poles) with new materials in which the larvae can not live. The larvae are entomophagous and feed on beetle larvae inside the wood. Andrenosoma albibarbe is restricted to the Alps and several southern European species can only be distinguished by the male terminalia.
