Abstract

A State-threatened White Sands pupfish (Cyprinodon tularosa) was captured by a fishing spider (genus Dolomedes) in a spring on White Sands Missile Range, New Mexico. Before it was able to consume its prey, a predaceous diving beetle (Cybister fimbriolatus) stole the pupfish from the spider's grasp. Depredation of pupfish by these two invertebrates has not previously been documented to our knowledge. Although it is likely not a significant mortality source for pupfish populations, the pupfish is nonetheless a potential food source for Dolomedes and C. fimbriolatus.
