|male Small Red-eyed Damselfly|
Apart from size the diagnostic features for male Small Red-eyed Damselfly are found on the abdomen, which is divided into 10 segments. Segment 1 (S1) is attached to the thorax, and the segments are numbered sequentially to Segment 10 (S10) which is the very end segment. On male Small Red-eyed Damselfly there is more blue on the abdomen, S1 is completely blue and blue is found on the side of S2 and even the underside of S3. On male Red-eyed Damselfly the blue near the thorax is confined to S1 only. The other difference lies at the the other end of the abdomen; male Small Red-eyed Damselfly show complete blue on S10 and S9 but also a significant amount of blue on the side and underside of S8. On male Red-eyed Damselfly the blue is confined to S10 and S9.
I've included a record shot of a male Red-eyed Damselfly, taken earlier in the year at Neath Canal, for comparison.
