Plunging a bucket into my water butt this morning to give the roses a bit of
help through the dry spell, I noticed four or five unfamiliar beasties
twitching in the drawn water.

Each is about a quarter of an inch long, mostly clear but with darker areas
transversely and a definite head end.

There is a very thin, quite short, breathing tube (I assume) at the other
end.

Not any variety of mozzie larva I know.

Any suggestions?
