Tiger bee fly

The mother fly does not go into the bee nest. She drops her eggs near the entrance, and the babies crawl in by themselves.

Like all flies, it has only one pair of wings that work. Bees have two pairs.

Looking like a bee helps it, because many animals stay away from things that might sting.

When it visits flowers for nectar, it can help carry pollen too.

You often see it near wooden fences and roofs, because that is where carpenter bees make their nests.
