Someone found a kind of spider which only eat plants. So this finding broke the assumption that all spiders are carnivore. Because of the unusual feeding habits, Eric found it interested and started his research. E&O work together found out that the jumping spiders don’t eat ant but eat vegetable.
But the Beltian bodies don’t have enough nutrient to support the spider. So how the spider adapt to this diet? There are bacteria in ant larvae help the spider digest the plant. Another question is why do this spider need neighbor. The purpose is living close may reduce the resource competition and reduce the aggression.
More spiders consume Beltian bodies , the less ant large left. Then the number of ant will reduce.
This circulation may destroy the spider-plant-ant system
So continued study will illuminate the rare species and the system made them.
