Milkweed beetle

Tetraopes tetrophthalmus

Description:

milkweed beetle, a herbivore, is given this name because they are generally host specific to milkweedplants (genus Asclepias). It is thought the beetle and its early instars derive a measure of protection from predators by incorporating toxins from the plant into their bodies, thereby becoming distasteful, much as the Monarch butterfly and its larvae do. The red and black coloring are aposematic, advertising the beetles' inedibility. There are many milkweed-eating species of insect that use the toxins contained in the plant as a chemical defense.

Notes:

In the family Cerambycida
