Fig. 7. The amount of time taken for ants to carry untreated mealworm segments,
segments covered with distilled water, and segments covered in regurgitant,
into one of their foraging holes. Note that two trials in which mealworms were
coated in regurgitant were not included for analysis, because the mealworms
were never accepted by ants. Values are means ± s.d. *Significant
difference (P<0.001).
