Black-tailed Skimmer
Orthetrum cancellatum
East Riding Status: A recent colonist to the area. Can be seen well at North Cave Wetlands were conditions are currently ideal for this species, however it may become less favorable as the site matures. Appears to be probably breeding at Tophill Low as numbers have increased over the last few years, though it is difficult to locate. Recorded with some regularity at Spurn with first records in 2004 from Welton Waters and Paull Holme Strays.
Flight Period: Nationally the flight period is from mid-May to late August. The chart below shows the flight period for the East Riding based on current records.
