An ant likes nectar, but being a crawling insect, its ability to forage on many flowers is limited. That is, unless it is a flying ant, and can quickly move from one flower to the next. The problem, though, is that sooner or later, there will be a flower hiding a killer, a crab spider.
A crab spider is an ambush predator that waits patiently on a flower for its meal to arrive. The spider grabs the prey with front legs and delivers a deadly dose of venom through its fangs. The venom’s effects are twofold: It paralyzes the insect; It digests the insect’s insides. The spider then uses its fangs like a straw to drink the insect’s insides.
A female crab spider (Misumena vatia) drinks the already digested insides of a flying ant.
