Conditions: Sunny, 80's
Start: 10:30 a.m. April 5
End: 5:00 p.m. April5
Habitat:Mature deciduous woodlands with Spring Beauty understory
Bees: Andrena, Osmia, Lasioglossum, Ceratina, Nomada - Many bees flying around
Experiment: 3.25 ounce white solo cups were alternated with a completely filled 12 ounce white party store cup and a half-filled white 12 ounce party store cup. Bowls were spaced 5 m apart and filled with soapy water (unscented laundry detergent and tap water).
Problem: I only sprinkled a little laundry detergent into the several gallons of water for the experiment...apparently this was not sufficient, as I saw bees land on the surface tension and fly or crawl out. I will go back to a more concentrated solution.
Despite low catch there was an indication of a bowl effect with the 3.25 ounce bowls. However, this needs to be repeated as the 3.25 ounce bowls had been used many times before and may have a lot of residual soap on them. The 12 oz. bowls had never been used before.
