Bugged by water beetles
I have a small 100 gal pond in Dunedin, FL. Some small black water beetles
are eating my water lily and mosaic plant. I was hoping the two 4" koi would take care of them, but no luck. Any suggestions would be greatly appreciated. Thanx, Rob P. |

I doubt they are aphids. They are approx 1/8-1/4 inch, hard black shell
and swim fast. I caught one the other day, it had a multicolored sheen over the black. At first only the lilypads where getting eaten, large chunks missing, then they moved on to the mosaic. I also had a small amount of duckweed which is completely gone. Sorry, I don't have a digital camera.

Do they swim in circles like demented bumper
cars? kathy :-) algae primer http://hometown.aol.com/ka30p/myhomepage/garden.html |

No, they're not Whirligigs. I've only seen them underwater. Two weeks ago
I saw one swim into a plant pot, I removed the pot, but never could find the little guy. Last week I removed a few of the iris plants because of the hurricane. When it was time to put them back in the pond, I caught two of them in the holding tank. One approx. 1/4" the other was very small, probably 1/8". From what I've found online they appear to be water scavenger beetles, maybe burrowing water beetles. Still not sure how to get rid of them. Thanx for the help, Rob P.

They should have to come to the surface to breath, whatever the little guys are. I remember Brett in Texas saying he used to pour oil on top of his water to kill off a type of beetle that was chowing down on his infant fish. Probably you can use something that is cheap, maybe corn oil? When you suspect they are all dead then overflow the pond and get rid of the oil. It is 100 gallons I think so it should be doable... If you try this let us know how it works for you. good luck! kathy :-) algae primer http://hometown.aol.com/ka30p/myhomepage/garden.html |

As visible as they seem to be, I'd hand pick (fish net) them out as you see
them. There are probably fewer than you think, and if they don't have time to lay eggs (may be the wrong time of year now) that should do it. ~ jan On Thu, 09 Sep 2004 21:19:20 GMT, RP wrote: No, they're not Whirligigs.

If they are indeed Tropisternus as your link implies, you can find a lot of
info on Google. Here's a link that upon reading supplies several good hints on how you might combat them: http://www.wlu.ca/~wwwbiol/bio305/Da...opisternus.htm It says the larvae are poor swimmers, moreover they pupate above the water line so you might be able to find and remove them then, too. Other than that, netting is often effective in a small pond although you'll have to make many passes over several days or weeks! Tim C. "RP" wrote in message ... I doubt they are aphids.
