The common milkweed (Asclepias syriaca), is a wonderful plant for many, many insects. Monarch butterflies are, of course, closely associated with it, as they lay their eggs on it and the larvae (caterpillars) eat the leaves. However, many insects love the nectar of milkweed and flies, bees, wasps, butterflies and beetles, as here, will land on the flowers to seek the sweet nectar. When they do, their feet sink into the individual florets in which are a little pollinarium, containing pollen pads, sticky little packets of pollen that adhere to the insects legs. When they pull them out and fly to the next milkweed, the pads are deposited in the new flowers and pollination occurs. But... sometimes the insects cannot free their feet and you will often find dead insects hanging upside down, caught! This soldier beetle was able to pull out his feet and so you can see the pollen pads or packets!
