Rare coastal species associated with Limonium-dominated saltmarsh.

Species text
This horsefly is sparsely recorded from coastal areas of southern England with records predominating in East Anglia and the Poole Harbour, Solent area. There are only about 15 known post 1960 sites within Hampshire, Kent, Essex and Norfolk and many of its old haunts are now either destroyed or unsuitable and its Essex populations are under particular threat from rising sea levels (Falk 1991a). The species occurs on saltmarsh and some shores with spits or bars of sand forming sheltered lagoons. It has been reared from a larva obtained in a core sample from Limonium saltmarsh in Essex and in Brittany, France the larvae have also been obtained from sand and seaweed at the drift line of shores. The normal breeding site may therefore be in saltmarsh or under seaweed and other drift material on the strand line where there is abundant and concentrated supply of food for the carnivorous larvae. Such drift-line debris may be found on sandy strands that occur locally at the landward margin of saltmarsh in sheltered lagoons, or it may accumulate directly on high saltmarsh (Stubbs & Drake 2001). Females have been observed sucking the blood of sheep and attacking humans, and both sexes feed on the flowers of sea lavender. References
