      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?
