Behavioral evolution accompanying host shifts in cactophilic Drosophila larvae
For insects living on plants, the shape and size of the plant should encompass its foraging environment and therefore affect behavior. Here, we show variation in locomotor and pupation behavior within and between species of cactophilic Drosophila that is related to the shape of the cactus they inhabit. Abstract For plant utilizing insects, the shift to
