Education/awareness raising

Raise awareness among the public of this species as it's a fairly distinctive and conspicuous species and would be noticed by casual observers. Given recent findings, other populations are probably to be discovered.

Scientific research

Define autecology of larvae and adults at known sites. Population genetics of known populations

Status survey/review

Targeted survey of known and similar sites

Untargeted habitat management

This species would benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages
