Finally to the cone traps. I made these to be suspended over small streams in the mountain, then never used them like this, the idea being that the insects could not simply fall out as they would from a malaise suspended over water.

I made two, the blue one used at Sultanitsa site and the Y#yellow one used at Helicopter, I was interested here in impersonating a giant flower. Sadly my brain wasn't working the day I bought the cloth for the yellow one and I bought too large mesh, so microhyms and such could just walk through the holes, I didn't notice this until the day I was putting it up.

The blue one worked excellently, catching loads of stuff. The yellow not so well, but again I think placement was a lot of the problem. I think they would work best where I designed them to go, over a small stream, with light behind them if possible. The Sultanitsa (blue) certainly was a success. See the taached phot of it in place.

They had the same catching bottle arrangement as the home-made malaise. I used domestic hot-water piping to make the support hoops, a bit of pipe, with a longitudinal strip cut out and glue, was used to connect the two open ends. I think maybe a wider mouth might have been better. I drilled holes through hoop (and cut them through the cloth) to insert wire to which the supporting string/rope was attached, (3 on the larger hoop) this allowed complets control of the traps placement.
