Fig 2. Drosophila predator avoidance in a circular arena with an alcove.
A diagram of the 8.2 cm diameter arena with a central cage and an alcove is shown in (a). To measure avoidance in this arena, the % time spent in the cove zone during the 10 min assay is shown. Canton-S males spend significantly more time in the cove zone when (b) a pantropical jumping spider (Plexippus paykulli) is present. In this arena, Canton-S flies did not significantly avoid (c) the twin-flagged jumping spider (Anasaitis canosa), (d) the Texas unicorn mantis (Phyllovates chlorophaea) nymph, nor (e) the non-predator milkweed bug (Oncopeltus fasciatus). ** p < 0.01. The middle line of each box plot represents the median, while upper and lower box display the 3rd and 2nd quartile respectively. The whiskers show the 90% confidence intervals.
