Typical habitats
Arachnocolus larvae are most abundant in bush-covered, gravelly streams with cool and well aerated water.
Feeding
Leptophlebiid mayflies feed by scraping diatom algae and other organic matter from stone surfaces.
Indicator value
- Hard bottom: 8
- Soft bottom: 8.1
The tolerance values (ranging from 0 to 10) give an indication of which are the sensitive taxa (values of 8 or more) and which are the tolerant taxa (values of 3 or less). For more information see: Indicator species
Arachnolocus are not often found in high abundance, but they are indicative of good habitat and water quality, especially if other mayfly or stonefly groups are abundant. Arachnolocus has tolerance values of 8 (hard bottom sites) and 8.1 (soft bottom sites).
