Over here we call these little critters 'water boatmen' or 'pond skaters' - I loved them as a kid! Used to catch them in my net and make them run over my hands... They're damn fast, eat small larvae, and are quite predatorial for their size. If I'm not mistooked they have a latin name like corixay or summik..... (I'm diggin this up from the memory banks, I can tell ya!!!) I believe the fly fishers among us may know of them, coz trout eat them, and I'm pretty sure there's a fly of the same name (corixay) for fishing....... See, not just a pretty face ;) (",)
