Late instar larvae of the scuttle fly, Megaselia scalaris Loew, were found near the right eye of a live captive-reared western hognose snake, Heterodon nasicus Baird and Girard. Dissection and removal of the snake's dorsal cranial bones revealed tissue degradation of the infected eye, the optic nerve, and the brain case; we suggest that these factors contributed to the death of this snake. This case study further demonstrates the opportunistic behavior of M. scalaris.
大眼粗腿蝇的晚期幼虫在一只活体饲养的西部菱斑响尾蛇（ Heterodon nasicus Baird and Girard ）右眼附近被发现。对蛇的颅背骨进行解剖和移除后，发现受感染眼睛、视神经和脑壳组织退化；我们认为这些因素导致了这条蛇的死亡。本病例研究进一步证明了大眼粗腿蝇的机会主义行为。
