Black-tailed Skimmer
Orthetrum cancellatum
This record describes Orthetrum cancellatum (species). Recorded family: Libellulidae. Recorded order: Odonata.
Identification and Appearance

A medium-sized dragonfly with relatively broad, flattened abdomen, but not as broad as the two chaser species. Mature males have a pale blue abdomen with pale yellow spots on the sides and a dark tip. Immature males and females are unmistakable, being mostly yellow with black vertical stripes. Often basking on bare waterside banks, in particular at recently dug ponds and gravel pits. Females are less bold and not encountered as regularly. This species only appeared in Britain in 1934. The adults feed from perches, often pouncing on butterflies, grasshoppers and damselflies. Mature males are territorial, protecting an area up to 50m of bank. Fairly frequent over much of England south of the Humber and in south Wales, less frequent elsewhere in Britain. The Black-tailed Skimmer, a species with a marked preference for recently created pools, was first recorded in VC 55 as recently as 1987. Since then it has become well established over the whole of the county and males basking on bare waterside banks are now a regular feature of the summer months, particularly in areas of mineral extraction.

About Dragonflies and Damselflies: the wider group
Order-level background for Odonata, the group containing Orthetrum cancellatum. Species-specific details appear above.
Group overview
Odonata includes ~6,000 described species of dragonflies and damselflies. Dragonflies are among the fastest flying insects, reaching 36 mph (58 km/h). They can fly in any direction including backward, and hover in place - each wing operates independently.
Ecological role of the group
Dragonflies predate dinosaurs by nearly 100 million years - fossils date to 325 million years ago. The largest dragonfly ancestor, Meganeuropsis permiana (285 mya), had a 75cm wingspan, enabled by atmospheric oxygen levels of 31-35% compared to today's 21%. Dragonflies have a 95% hunting success rate - the highest of any predator.
Economic and practical significance of the group
Dragonflies are voracious predators that consume hundreds of mosquitoes daily, providing natural pest control worth millions in reduced mosquito-borne disease risk. A single dragonfly can eat 30 to hundreds of mosquitoes per day.
