Isle of Wight Dragons: Southern Emeralds Clock Up Five.

Monday 1 October 2018

Southern Emeralds Clock Up Five.

The Southern Emerald Damselflies at Bouldnor are now in their fifth calendar month since the first sighting at the start of June.Today's individuals were again seen at the smaller scrape with just two males and an attached pair.It is clear to see that the once metallic green colouring is now bronze with age.

Golden-ringed Dragonfly

This is our largest UK dragonfly and seems to be widespread on the Isle of Wight.It is readily found along suitable streams and small rivers.

The male has a swollen abdomen at the tip while the female can be identified by a long and pointed ovipositor which is used to jab repeatedly down into the bed of shallow water to lay its eggs.

The larval stage can last up to five years as the larvae will spend their time buried at the bottom of the watercourse,with eyes only protruding,waiting to grab passing prey.
