Karim Vahed FRES is a British entomologist. He is a professor of entomology and England manager at invertebrate conservation charity Buglife, and is an expert in crickets and bushcrickets (katydids).[1][2]

Education and career

Vahed has been fascinated by insects since childhood.[3] He studied biological sciences at the University of Exeter[3] 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.[4] In 1993 he joined the University of Derby, eventually becoming Professor of Entomology.[3] and Programme Leader for the masters programme in conservation biology.[5] In 2022 he moved to Buglife to become England Manager.[6]

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.[7] He has studied the behaviour of giving nuptial gifts in insects.[8] 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.[9][10] The large testes enable the insect to mate more frequently.[9]

Vahed is involved in conservation of rare orthopterans and monitors the rare scaly cricket (Pseudomogoplistes vicentae) on the UK mainland[5] as well as on the Channel Islands including a potential new colony of the species on Guernsey.[11][12] On Guernsey he performs surveys of the cricket with volunteers from La Societe Guernesiaise.[12] He has campaigned against making the Guernsey site a waste dump.[13] He also studies the mating behaviour of the scaly cricket.[5]

In 2014 Vahed was interviewed on BBC Four television documentary Spider House by Tim Cockerill,[14] in 2019 he appeared on The British Garden: Life And Death On Your Lawn with Chris Packham.[15]

Awards and honours

Vahed is a Fellow of the Royal Entomological Society,[16] 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.[17]
