In June of 2011, collecting partner and laboratory colleague, Zong Hang Yang with WH collected for an evening at Aowanda National Forest Recreation Area, Nantou county. The site had been closed to the public for some time due to devastation caused by Typhoon Morakot, the previous year. Because of this, there was an abundance of deadwood and fallen trees in the area, being reclaimed by the land for several months. Situations like this can present an excellent opportunity for the collection of pericaline lebiines, due to their association with both the insects and fungi that require and use these microhabitats. That evening WH came across a broken stump that had the north side of it covered in a large patch of frilly, white, bracket fungus; within the folds of this fungus, were numbers of a large adults of large erotylid beetle (

The erotylids and their larvae did not seem to be bothered at all by the presence of the carabids around them. Specimens of the erotylid beetle, the carabids, and also some larvae and associated fungus were collected. Upon researching this type of behavior, a paper by
