Table 2.

Grouping tendencies of L. delicata and L. guichenoti, indicating the proportion of time spent associating with each stimulus during the six dichotomous choice experiments. The results of the paired t-tests are indicated. No comparisons were found to be statistically significant following Bonferroni correction
