Typical habitats

This recently discovered mayfly is only known from a North Cape stony coastal stream in an area of native bush, but it is possible Aupouriella occurs in other areas.

Feeding

Leptophlebiid mayflies feed by scraping diatom algae and other organic matter from stone surfaces.

Indicator value

Aupouriella is only known from a single stream flowing though an area of native bush, and native bush streams generally have good water quality. There are no tolerance values for this mayfly.
