The red beetles are in the family of longhorn beetles, Cyrambycidae -- notice the long antennae. Not to be confused with the much more common Milkweed Bugs, which are also red and black, but are not even beetles. Milkweed Bugs are in the order of true bugs, Hemiptera.
It's not a coincidence that Red Milkweed Beetles, Milkweed Bugs, and Monarchs all are red or orange, which are "warning" colors to birds and other predators, meaning do-not-eat-me-or-you'll-be-sorry. The Monarchs and Red Milkweed Beetles and Milkweed Bugs are toxic to predators because of toxic chemicals in the milkweed they eat.
