These 2 mating bugs are the Large Milkweed Bug, Oncopeltus fasciatus, they are true bugs. Beetles, moths, flies, and butterflies are not. Bugs have the usual complement of structures that they share with just about all other insects: six legs, three body parts (head, thorax, and abdomen), and two antennae. True bugs (order Hemiptera) do not have mouths for biting and chewing food—they have a tubelike beak for sucking fluids. The milkweed bug in nature sucks nutrients from milkweed seeds.
Milkweed bugs are one of a small group of insects that have the ability to tolerate the toxic compounds in the milkweed plant. They are therefore important in regulating populations of this plant.
This type of milkweed shown here is the Butterfly Weed, asclepias fuberosa more will be said of it on another shot
