Smivs writes: "The BBC are reporting on a spider that dines almost exclusively on plants . It is the first-known predominantly vegetarian spider; all of the other known 40,000 spider species are thought to be mainly carnivorous. Bagheera kiplingi, which is found in Central America and Mexico, bucks the meat-eating trend by feasting on acacia plants. The jumping arachnid, which is 5-6mm long, has developed a taste for the tips of the acacia plants — known as Beltian bodies — which are packed full of protein. To reach this leafy fare, the spider has to evade the attention of ants, which live in the hollow spines of the tree, but the crafty Bagheera kiplingi has found a way to evade the ants and safely reach it's food."
