Eristalis abusiva Collin, 1931
Biology & ecology:
The larva is of the ?long-tailed?, aquatic type, and is associated with wet, decaying organic matter such as that around ponds. It has been found at the edge of a pond on moorland (Smith, 1989). Adults are usually seen visiting flowers around the edges of scrub, hedges and tall vegetation near the larval habitat.
Although widely distributed, this species is rarely encountered inland. Most records are coastal, especially from the west coast. Records extend north to the Island of Lewis in the Outer Hebrides and to Mainland Shetland. It is possible that this species is overlooked as most recorders expect to encounter it in coastal localities but it does occur inland.
Status & conservation:
There has been a decline in occurrence since the 1990s.
