| ADULT |
Wingspan - 65mm. A stunning creature with a total length up to 50mm this is a much sought after species and well worth the effort. Tenerals are basically yellow and black whereas mature male specimens are a combination of a gentle pale green and black except for the flanks of abdominal segments 8 and 9 which remain bright yellow. Females generally have heavier clubbed tails. Both sexes have eyes which do not meet in the centre |
