Black Darter (Sympetrum danae). A small darter that appears in late summer and the mature male is easily recognised by its obvious black colour, black legs, black pterostigma plus the waisted abdomen but not so easy to capture on a windy, overcast day are the three yellow spots on black patch on the side of its thorax! The females and immature males are yellow changing to an olive shade as they age.
This pair were very fidgety during copulation which made focusing somewhat of a challenge.
Females have a small yellow patch at the base of the wings that is just visible in these last two images.
Next time I'll try to pick a sunny day with no wind! FAB.
P.S. Update on PJB - Now breathing unaided but kidneys not working (hence continued dialysis) and liver only working at 25%. Expected to have a scan sometime tomorrow when hopefully we may learn if there are any other complications.
