Description

Tramea loewii is a medium to large dragonfly (wingspan 85 mm, length 45 mm). Its synthorax is striped yellowish to brown on a purplish background. Males have a red abdomen, and the last two segments have black markings. Females are a dull brown colour. Dark patches at the base of their hindwings are a characteristic feature of this species; males have red patches and females have brown. Tramea loewii is very similar to Tramea stenoloba which has a darker synthorax, and larger genital dimensions.[3]

Habitat

Tramea loewii inhabits a wide range of still waters, ponds and swamps, and may breed many times in a year. In Australia it is widespread except for the far south-west of the continent.[3]

gollark: But I guess being able to model how computers work is useful for programmers since many people are so very bad at this.
gollark: I'm not sure it's actually testing things relevant to programming skill by making you effectively *be* an inefficient computer.
gollark: A "computational thinking" challenge.
gollark: Not really. Besides, I was actually very good. Shame I couldn't do them for A-level.
