Average captures of marked lady beetles, C. septempunctata, within and between soybean and alfalfa fields in 2013 (a) and 2014 (b). Lower case letters represent significant differences (p < 0.05) between captures of marked lady beetles within and between fields (overall Kruskal-Wallis test followed by Kruskal-Wallis pairwise comparisons adjusted by Sequential Bonferroni). When one of the treatments was zero, a one sample t-test with Ho Mean = 0 was used. Movement directions: Alf↔Alf: alfalfa to alfalfa, Sb↔Sb: soybean to soybean, Alf→Sb: alfalfa to soybean, Sb→Alf: soybean to alfalfa.
