Dwell time after specific antennal contact patterns

	Over/over			Over/under			Under/under
	Mean (s)	n	Mean (s)	n	Mean (s)	n	Mean (s)	n
Light	2.96±1.8	6	2.56±1.89	15	1.80±1.98^a	33	2.14±1.95^b	54
Dark	1.79±1.61	8	4.07±3.8	27	3.37±3.67^a	25	3.48±3.55^b	60

This is a measure of the time between initial antennal contact and the initiation of climbing or tunneling behavior. Note that the mean dwell time(s) of all trials in the dark is significantly longer than that of individuals in light (P<0.05 Tukey means comparison). Furthermore, the dwell time for individuals whom contacted the shelf with both antennae under is significantly shorter for individuals in the light than it is in the dark(P<0.05 Tukey means comparison). It should also be noted that the shortest dwell times occur in the dark when both antennae are on top of the shelf and in the light when both are underneath, which may suggest preference for a specific side of the shelf in these conditions
