Ischnura pumilio (Scarce Blue-tailed Damselfly)
It took us a long time time to find some examples of these and then it required a little help from our friends. However, we finally did find the Latchmore Brook population in 2016. Interestingly, there used to be some in our home county of Bedfordshire until “conservation” changed their habitat and they disappeared.
The males resemble I. elegans but are smaller and the tail light is shifted. The species has a strong preference for shallow water with little vegetation. The striking orange colour of the immature (aurantiaca) females is much sought after.
- short bi-coloured pterostigmas, larger in fore-wing than hind-wing.
- ♂ – blue or green coloured eyes and thorax.
- ♂ – blue tail light shifted down (cf. I. elegans) on back half of S8 & S9.
- ♀ – no tail light
- ♀ – rather dull green when mature
- ♀ – stunning orange when immature; the so-called aurantiaca phase.
