Our Island Resident Species-Damselflies(2).

The Common Blue Damselfly as the name suggests is a species that can be seen throughout the UK. It prefers large water bodies such as lakes, reservoirs, and larger ponds. Of course the male is a striking blue and  the female has two colour forms, dull green and blue. The male and tandem pairs are often seen flying low over open water 












Another blue damselfly is the Red-eyed Damselfly which is quite commonly seen here at large ponds and standing water bodies, particularly with floating vegetation  such as water-lilies. Females and immatures tend to be yellowish-green in colour and new emergents have purple tones in both male and female. They can sometimes be in the company of the Small Red-eyed Damselfly although the former is on the wing in May whereas the Small Red-eyed emerges in late June or July.








Similar in appearance to the Red-eyed is the Small Red-eyed Damselfly. This species was  first recorded only twenty years ago on the Isle of Wight and has now spread around the Island. It too likes ponds with surface vegetation but is quite happy in smaller ponds unlike the Red-eyed. Females can be yellow, green, or blue.
