Start: Morning, 27 March
End: 5:00 p.m.31 March
Habitat: Patuxent River, bottomland, young deciduous woods, many spring beauties in bloom
Bees: Andrena primarily
Experiment: 9 sets of 4 bowls. At each set was 2 3.25 ounce white solo brand bowls and 2 Styrofoam 16 ounce cups laid in small square a bit more than one foot apart. Each type of bowls was filled either with a detergent mix or a glycol mix (Walmart RV antifreezed, dyed red). The capture was not removed the entire time.
Site Numbers are in the first row. "n" refers to a bowl that was spilled or had no liquid.
Interpretation: It is clear that there is a strong difference between the Plastic cups and the Styrofoam cups but not between glycol and soap.
