Notes

The galls of E. leai are the most conspicuous of those made by SA Ethonion species, and appear as distinct well-defined elongate swellings on the base or lower parts of stems.

Host plant notes

In SA the galls are normally found on Dillwynia hispida (Downy Parrot-pea) although there are also a few records from D. glaberrima (Smooth Parrot-pea) in the SE Region. Adults are most commonly found on flowers of the larval host species.
