Romalea microptera

“Eastern lubber grasshopper”

Figures 63 (lateral), 64 (dorsal, ventral)

Plates 38 (lateral), 39 (dorsal), 40 (ventral)

The tracheal structure of the lubber grasshopper Romalea microptera features a substantial number of air sacs, integrated into the tracheal system, and discrete air cells distributed throughout the body, especially the head and thorax. Due to the complexity of the tracheal architecture of Romalea, only spiracles and major tracheae are labeled in the plates. 3D models are provided in the supplementary digital data for further investigation.
