Re: [beemonitoring] Pan Trap Colors
Hi Gidi, I use small pan traps blue, white, red and yellow simultaneously, filled with water, detergent and a little of sugar. I cached more bees in blue and yellow, only one type of small Halictidae in the white) in the red and white I obtain more diptera and also some butterflies.

1. I was wondering if anoyone has worked with bowl traps colored pink
or violet, and if so, what were the results. A substantial fraction of
flowering species, including bee-pollinated ones, have these colors.
Where I come from (Israel), they greatly outnumber the blue ones.
2. Did anyone find any significant difference in bee
species/genera/ taxon/functional group composition, when comparing the
catches of white, blue and yellow bowls?
