I am not quite sure qhat you mean by 'collected fly under water' but
R. crassirostris can swarm very close to the water surface (or at least males hunt very close to it) and they are thus prone to get into the water when you sweep close to the surface. And there probably other other reasons that a specimen may get submerged...
