Scarce Chaser Exuviae

Whilst at Westbere Lakes a few days ago photographing dragonflies, I was moving into a better position for some photos when I caught sight of a dragonfly exuviae on a reed at the side of the river. I have mentioned in previous posts about my desire to find a Scarce Chaser exuviae and I just knew with its location and seeing it was a Chaser exuviae, that it was going to be a Scarce Chaser. Having never seen one before but having read and looked at photos in books and the internet, there was one obvious feature in mind that I needed to check, this being the dorsal spines which are long and curved. I should have taken a few photos of the exuviae on the reed but it was in a position just hanging over the water and awkward to photograph but in the excitement of finding it, I just carefully removed it and put it in a plastic pot to be brought home to be photographed. I then spent an evening studying and photographing the exuviae at home where I was able to study notes in books with what I was actually seeing, thus hopefully deepening my knowledge in this area of odonata. Considering I have not been seeing many Scarce Chasers at Westbere this year, I think I was very fortunate indeed to find this one and maybe should spend more time actually with the camera in the bag and looking for the exuviae of different species. I shall continue to look for Norfolk Hawker exuviae in the dykes at Westbere but so far, this species still eludes me. Hopefully weather permitting, a visit in the week to see the Norfolk Hawkers at Westbere which seem to be slowly appearing in the dykes.

    1. Many thanks Bob. They may be alien looking but I do like to find and photograph an exuviae.
