Green-eyed hawker

Aeshna isoceles

''Aeshna isoceles'' is a small hawker dragonfly that is found in Europe, mostly around the Mediterranean, and the lowlands of North Africa. Its common name in English is green-eyed hawker. In Britain it is a rare and local species and is known as the Norfolk hawker.

A year has passed, and this species continues their life cycle as predicted, since early spring!
The same question remains, either two generations, or species resilience which can comprove summer diapause.
Twelve individuals spotted, 2 females, 10 males. The species is here for Autumn! 
This is the only location so far, where this species can be classified as that, as an Autumnal species. Aeshna isoceles,Green-eyed hawker,aeshnidae,anisoptera,biodiversity,dragonfly,insecta,odonata

Appearance

''A. isoceles'' is one of only two brown hawkers found in Europe, the other is ''A. grandis''. Both have a brown thorax and abdomen but ''A. isoceles'' has green eyes and clear wings and a diagnostic yellow triangular mark on the second abdominal segment. The hindwings have an amber patch at their base. In contrast ''A. grandis'' has yellowish wings and blueish eyes. The green eye of ''A. isoceles'' stand out even in flight and in practice it is not difficult to tell these two dragonflies apart. In addition to the morphological differences ''A. isoceles'' is on the wing much earlier in the year than ''A. grandis''.

Distribution

''A. isoceles'' is found in central Europe and around the Mediterranean and, the lowlands of North Africa. It is more common in eastern Europe than the south western Europe; it occurs in Spain and Portugal but is local.

It is found wet areas, ponds, ditches and marshes, with dense vegetation and, in studies carried out in England, was found to be associated with Water-soldier .

Status

The Norfolk hawker has always been a scarce and local insect in Britain. It used to be found in the Cambridgeshire fens but by the early 1980s the populations had greatly declined. It is now confined to relatively unpolluted fens and grazing marshes in the Broadlands of Norfolk and north-east Suffolk. It can be found in Hickling Broad and two national nature reserves: Mid-Yare NNR and Ludham - Potter Heigham NNR and at Castle Marshes in the Barnby Broad and Marshes SSSI. It is protected under Schedule 5 of the Wildlife and Countryside Act 1981 and listed in Category 1 in the British Red Data Books on Insects.
Aeshna isoceles Aeshna isoceles, adult female. A little story for today... At 16:00 o'clock in the afternoon, a clouded sky remind me that this was the end of the day. Although a bit late, and with scarce light, this dragonfly appeared. Well, this dragonfly, in which i don't know more what to think about... well, we are november, that's a fact. This species is still up, that's a (crazy) fact... and there's more, as a female, the evidences of adulthood should be present, like fading blured orange through over its body, stripped/bite/ragged wings due to male captures, and so on... but no, this female looks like that hatch up a few weeks ago... well, as I was saying, I don't know what to think more... I'm dazzled.  Aeshna isoceles,Green-eyed hawker,aeshnidae,animalia,anisoptera,arthropoda,biodiversity,insecta,odonata

Behavior

It is one of the earliest ''Aeshna'' dragonflies to be on the wing with a flight period from May to August. Adults do not spend as much time on the wing as other ''Aeshnas''. Males will fly around over a stretch of water defending a territory and if the pond is small the male will hover over the centre of the pond. Unlike other aeshnas, where the adults seem to be continuously on the wing beating up and down their territory, male ''A. isoceles'' come to rest on vegetation from time to time. Females oviposit onto plants and the eggs hatch in about 2 weeks. Larval development takes 2 years.
