Introducing Gloucestershire’s Robberflies

Adult robberflies (Order: Diptera, Family: Asilidae) are effective daytime hunters, relying on sight to target moving insect prey which they then seem able to immobilise by injecting posion through their mouthparts. Martin Matthews has prepared a basic introduction to the adults of the 16 species of robberflies (12 of them illustrated) that have been recorded in Gloucestershire at least once since 1950. The guide can be downloaded from the invertebrates section of our publications pages.
