Lunar Hornet Clearwing Moth found on a survey in Manchester City Centre

Sunday, July 7th, 2013

The Lunar Hornet Clearwing Sesia bembeciformis, is a more common relative of the Hornet Clearwing Sesia apiformis, both species are in fact moths. They imitate hornets in appearance, flight and they even emit a buzzing sound when flying.

Hornet moths are a fantastic example of what is known as ‘Batesian mimicry’ where harmless species have evolved to imitate more harmful or distasteful species. The idea being that predators are likely to avoid the harmless moth based on a previous unpleasant experience with a hornet or other similar species.

The caterpillars are most often found in willow trunks and can remain in the larval stage for up to two years before emerging as a moth. This photo was taken in Manchester City Centre.

 

Moth monitoring surveys

Tuesday, August 23rd, 2011

UES have now spotted 72 species of macro-moth so far during monitoring surveys, including the Lime-speck pug moth. Moths with narrow outstretched wings are ‘usually’ pug moths, members of the Eupithecia family.

The Lime-speck pug is very distinctive with its lime white wings and large dark ‘speck’ on the leading edge of wing. It is thought that this species may resemble a bird-dropping and thus reduce attraction to predators.

Other species observed recently include Dark arches, Flame carpet,  Small phoenix, Buff arches, Buff tip, Common wainscot, Early thorn, Light arches, Riband wave, The Clay and The Olive moth.

Moth monitoring surveys

Tuesday, July 19th, 2011

There are over 2500 species of moth in Britain. As there are so many species of moths, experts split them into two groups, the larger (or macro-) moths and the smaller (or micro-) moths.

UES has been lucky enough to spot 51 species of macro-moth so far during monitoring surveys, including the impressive Eyed hawk-moth so called due to the large and beautiful spots on each of its hind wings, and the Peppered moth whose white with black speckled patterning across the wings make it well camouflaged against lichen-covered tree trunks which it rests on during the day.

Other favourite species observed include Burnished brass, Elephant hawk, Garden tiger, Ghost, Light emerald and Lime hawk-moth.

UES contributes to the National Moth Recording Scheme (NMRS), which brings together sightings of all macro-moths across the UK, Isle of Man and Channel Islands in a bid to create full ‘Britain and Ireland’ distributions for all species.
