Education and career

Vahed has always been fascinated by insects.[2] He studied biological sciences at the University of Exeter[2] and did a PhD at the University of Nottingham on the function and evolution of nuptial feeding in bushcrickets, focusing on the role of the spermatophylax.[3] In 1993 he joined the University of Derby, eventually becoming Professor of Entomology.[2] At the University of Derby he is the Programme Leader for the masters programme in conservation biology.[4]

Research

Vahed's research looks in particular at the sexual behaviour of the Orthoptera order of insects, the crickets and bush crickets and related groups.[1]

He discovered a group of bushcricket species Anonconotus sp. that are able to mate many times without need to recover.[5] He has studied the behaviour of giving nuptial gifts in insects.[6] His team also discovered a cricket species Platycleis affinis in which the testes accounted for 14% of the insect's body mass, the largest percentage of any animal at the time of the study.[7][8] The large testes enable the insect to mate more frequently.[7]

Vahed is involved in conservation of rare orthopterans and monitors the rare scaly cricket (Pseudomogoplistes vicentae) on the UK mainland[4] as well as on the Channel Islands including a potential new colony of the species on Guernsey.[9][10] On Guernsey he performs surveys of the cricket with volunteers from La Societe Guernesiaise.[10] He has campaigned against making the Guernsey site a waste dump.[11] He also studies the mating behaviour of the scaly cricket.[4]

In 2014 Vahed was interviewed on BBC Four television documentary Spider House by Tim Cockerill,[12] in 2019 he appeared on The British Garden: Life And Death On Your Lawn with Chris Packham.[13]

Awards and honours

Vahed is a Fellow of the Royal Entomological Society,[14] of the Royal Society of Biology, of the Linnean Society and is a Senior Fellow of the Higher Education Academy.[1]

Personal life

Vahed and his partner, Kate Bellis, a photographer, have one son.[15]
