Description

Learn about the Soldierflies (Asilidae) of the UK with tutor Martin Harvey.

Webinar poster, showing a Bumblebee RobberflyRobberflies (family Asilidae) are a group of true flies with 28 species known to occur within the UK. The group gets its name from their ambush-predator lifestyle, capturing their insect prey in flight, using swift, darting attacks and then injecting digestive enzymes through a sharp proboscis to immobilise and consume their prey. They are typically slender or robust, often bristly, with strong legs and a characteristic facial “moustache” (the mystax) that protects them from struggling prey.

This entoLEARN webinar will introduce robberflies as a family and then cover a range of robberfy species that occur within the UK, including the following:

  • Robberflies on the beach: The sand dune species Dune Robberfly (Philonicus albiceps), Pied-winged Robberfly (Pamponerus germanicus) and Spring Heath Robberfly (Lasiopogon cinctus).
  • Scottish specialities: Northern Robberfly (Rhadiurgus variabilis) and Bumblebee Robberfly (Laphria flava).
  • The enigmas: Rare and extinct species Devon Red-legged Robberfly (Neomochtherus pallipes) and Ginger Robberfly (Choerades gilvus).
  • Hornet Robberfly (Asilus crabroniformis): The largest fly in Britain and a voracious predator.

Entomologist Martin Harvey will provide identification guidance and insights into the ecology and behaviour of these fascinating insects, as well as information about how you can submit your sightings to the Soldierflies & Allies Recording Scheme.

Cost: £12.50.
