. “Traplines are learnt foraging routes along which food sources are repeatedly returned to over consecutive days, an efficient foraging strategy similar to the behavior of some orchid bees and bumblebees. However, the spatial learning abilities of Heliconius, or indeed any butterfly, had not yet been experimentally tested.”, the team conducted spatial learning experiments in Heliconius butterflies over three spatial scales that each represented ecologically-relevant behaviors.
Next, the team increased the spatial scale and tested if Heliconius could learn to associate food with either the left or right side of a two-armed maze, to represent multiple plants at a single place. in southern France to test if Heliconius can learn the location of good in a 196 foot wide maze shaped like the letter T. This set up represents foraging between places and is closer to the range Heliconius forages in in the wild.
