Snake-flies, alderflies, lacewings and scorpion flies in Essex
the males, the tip of the abdomen of which bears a swollen genital capsule, which is held forwards
over the body in a manner similar to that in which a scorpion carries its sting. Scorpion flies do not
posses a sting, however, and are totally harmless.
Panorpa cognata Rambur, 1842
National status: Local (Notable)
Predicted county status: Rare/-
Distribution
There is only one Essex record - from Tiptree
Heath on 29 August 1982.
Habitat and ecology
The least known of the British scorpion flies, its
habitat requirements are poorly understood.
Across the whole of Britain it is most often
associated with brambles on calcareous soils; this
scarcely describes the habitat at Tiptree Heath.
However, it is also noted from wet woodland and
tall vegetation.
Threats
None known, though the species is rather
uncommon nationally and efforts should be
undertaken to increase knowledge of its autecology so that any potential threats can be determined.
Etymology
From the Latin cognatus = related, similar or from the same stock, as first used by Pliny in discussing
the relationship of differing kinds of animals and trees. Rambur's name implies that this species is
similar to previously described Panorpa species.
Panorpa communis Linnaeus, 1758
National status; Common (Common)
Predicted county status: Common/-
Distribution
Widespread across the whole of Essex.
Habitat and ecology
This very common species has been encountered
in a wide range of habitats, all of which feature
rank herbage of one form or another, generally
in association with brambles or scrub. The
general impression is of an insect associated with
edge habitats.
Threats
None perceived.
Etymology
From the Latin communis = universal, occurs
everywhere.
