A more thorough approach is to allow emergence of adult specimens from the log. Emergence chambers were made using 18-gallon (ca. 68-L) Sterilite® plastic tubs that were modified by adding a removable bottom collection cup and ventilation to the top and side.
Ninety emergence chambers were filled three-fourths full with dead wood of various decay classes, placed in a shaded location, and serviced monthly for 24 months in Great Smoky Mountains National Park.
Here we illustrate details of chamber design and discuss time budget and collection efficiency of these contraptions. A total of 5692 adult Coleoptera representing 51 families, 226 genera, and 275+ species were collected. Selected results are presented to illustrate the effectiveness of the design. We also compare this design to other published and unpublished emergence chamber designs.
