Hornet robberfly
The hornet robberfly, ''Asilus crabroniformis'', is a species of predatory insect of the Asilidae family.
Reaching more than 25 mm in body length, it is one of the largest flies in the United Kingdom.〔Express and Echo, ''More info needed about deadly predator'' 21 May 2009〕〔http://www.arkive.org/hornet-robberfly/asilus-crabroniformis/〕 and feeds on grasshoppers, dung beetles and other flies.〔The Daily Telegraph, ''Brownfield building puts rare insects in jeopardy'' 3 May 2006〕 Unlike an actual hornet, the robberfly only has one yellow patch on its abdomen and one pair of wings. The larvae are believed to feed on dung beetle larvae and other detritivores.〔
''A. crabroniformis '' can be found in woodland clearings and well-drained areas of heaths and downs covering Southern England and South & West Wales. It is reliant on the availability of rabbit or cattle dung.〔p15 ''Land & Business'', November 2010, CLA〕
It is a member of the robberfly family Asilidae, subfamily Asilinae and is included in the list of endangered species in the British Isles.
