ORDER BLATTODEA

Three roaches were scanned during the study: the common American cockroach Periplaneta americana , the popular Madagascar hissing cockroach Gromphadorhina portentosa , and Blaptica dubia . The tracheal system of Gromphadorhina has been studied via dissection to determine the physiology of its hissing behavior ( Nelson, 1979; Nelson and Fraser, 1980) and was micro-CT scanned in a demonstration of semiautomated segmentation techniques (Lösel et al., 2020). Active tracheal compres- sion in Blattodea was studied via synchro- tron imaging by Westneat et al. (2003).

Periplaneta is described here in detail. As with other complex specimens, the other two roaches, Gromphadorhina and Blaptica, are only briefly described. Readers are directed to the labeled 3D models in the supplemen- tary digital data for further investigation.
