Description and habitat

It is a big dragonfly with blue eyes, pale green thorax and dark brown abdomen with bright yellowish-red markings on the sides. Its wings are transparent; but there are brown patches on the inner half of the hind-wings. Segment 1 and sides of segment 2 of the abdomen are pale green. The dorsum of segment 2 is blue with a narrow and broken transverse carina in the midst of the segment in addition to the broad terminal carinae. The dorsal side of segment 3 is blue with a black longitudinal mid-dorsal black line and sides are silvery white. The remaining segments are dark brown with yellowish-red dots on the sides. Segments 4 to 6 are with a pair of bright yellowish-red spots. On 7-8 these spots combine to form a continuous yellow band. Segments 9 to 10 are with a pair of large yellowish-red spots. Anal appendages are dark brown; the superiors have a triangular projection at the middle of their inner margin.[5][6]

This dragonfly looks similar to Anax guttatus; but can be identifiable by contiguous yellow spots on the posterior abdomen segments (7-8). They are not connected in Anax guttatus.[5][6][7][8]

Females is similar to the male. But the blue on the dorsum of segment 2 will be broken up into four by a narrow brown mid-dorsal carina and a transverse line lying midway to form a cross like mark. Anal appendages are very broad and shaped like lance head.[5][6]

This species breeds in ponds, marshes and lakes.[1]

gollark: I guess you could just have `unsafe`/`average_c` blocks for that.
gollark: Pointer arithmetic, for one thing?
gollark: Rust was designed with ownership to start with and still can't satisfactorily chëck everything. C code is typically a horrible minefield of unsafe everything so a borrow checker could have problems.
gollark: > someone, quick! a borrow checker for C<@356107472269869058> Isn't that impossible without stupidly high false positive rates and/or missing many unsound things?
