Euschoengastia pipistrelli (Acari: Trombiculidae) from American Perimyotis, Perimyotis subflavus (Chiroptera: Vespertilionidae): Novel Stereoscopic and Scanning Electron Microscopy

The chigger, Euschoengastia pipistrelli Brennan, is a trombiculid mite that infests a variety of vespertilionid bats in North America. It has been reported from at least 9 species of bats from 18 U.S. states. However, nothing is available on the actual in situ infestation and ultrastructure of this chigger. Here we document some stereoscopic photographs of the infestation as well as a scanning electron micrograph of the mite from a common bat species. We also provide a summation of host and state records for this chigger.
