Milkweed tussock moth caterpillar
The hairy caterpillars of the milkweed tussock moth or Euchaetes egle look like a cross between a bristle brush and a really fluffy dachshund. They have alternating tufts of orange, white and black, which explains why they're also sometimes known as the milkweed tiger moth. When they transform into butterflies, their wings are grayish, while their bodies are yellow with a row of black dots. The best place to find one of these tricolor insects is on a milkweed plant, of course.
