According to research published in the journal Current Biology, a spider found in Central America and Mexico, Bagheera kiplingi, is vegetarian.
(It feeds on the green tips of acacia plants. Of all the known species of spider, around 40,000 of them, these are the only ones that are vegetarian, although some spiders will occasionally supplement their diet with a little nectar or pollen, and according to scientists this species has been caught munching on the occassional ant larvae – a bit like vegatarians who eat eggs I guess.)
I just thought of a new line for that famous Cure song. Spiderman is having peas for dinner tonight.
