Specimens of toad fly needed!
The toad fly, Lucilia bufonivora, is as an obligate parasite of toads and frogs in Britain and Europe; it causes considerable suffering to infested host amphibians. Infestations typically begin in the nasal cavities and can spread rapidly throughout the head, leading to blindness and a lingering death. This fly is recognised as the only obligate parasitic blowfly species in Britain and to date, only a handful of specimens of this enigmatic fly species have been studied.
