Compared with other species:

The green colour and thorax markings make this species easy separate from other Spreadwing species. Characteristic is the sickle-shaped, whitish appendages that are relatively flat and pale cerci, with the tips of cerci bent distinctly downwards, rather than towards each other.

Distribution and habitat:

Localized in Northern KZN and MP Lowveld. More demographic data required to establish the true range of the species.
Its preferred habitat is margins of pools with tall grasses and sedges next to thick bush or forest, also occurring around murky waterholes with adjacent bushes.

Behaviour:

It hangs from tall stems over water, but retreats into bushes when disturbed.
