Confidence: I'm as sure as I can be.
Notes: The male is similar in appearance to its close relative Ischnura elegans, with the upper surface of the abdomen being entirely black, apart from a blue band spanning segment 9 and extending slightly into the posterior of segment 8. This differs from I. elegans where the blue band is restricted to abdominal segment 8. I. pumilio has a small black mark, one on either flank of the upper surface of segment 9. The extent of this black mark is somewhat variable.
