Bush dragonfly (Uropetala)
Taxonomic group
Petaluridae: Uropetala
Diagnostic features
Uropetala is a large dragonfly having a large larva with a long abdomen. The larvae appear heavily armoured (though without spines) and the legs are very hairy. The labial palps (jaw-like structures used to grab prey) lie flat under the head when at rest.
Typical habitats
Uropetala larvae are rarely recorded because they burrow into the mud of wetland margins – habitats that are rarely sampled.
Feeding
They are predators, feeding on other stream invertebrates.
Indicator value
- Hard bottom: 5
- Soft bottom: 0.4
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
Uropetala are inhabitants of wetlands rather than streams and they probably have little value as water quality indicators. They have medium to low tolerance values of 5 (hard bottom sites) and 0.4 (soft bottom sites).
