Flower Crab Spiders
This square-headed wasp landed on a flower perhaps looking for food. However, another animal was waiting. Crab spiders camouflage to match the flowers on which they wait for their prey.
Earlier in the summer, another crab spider waiting on a different flower, used its web to pull the petals up giving it shelter in which to wait. The pulled up petals are visible behind the spider in the second photo.
