Bee Flies' Courtship

We sometimes see two Bee Flies flying together, one larger and one smaller. The larger Bee fly chases the smaller one. When the smaller Bee Fly rests, the larger rests a few cm away. When the smaller Bee Fly flies, the larger follows closely.

In the insects world, usually the females are larger in size. When courtship, usually the males chases the females. In this case, since the larger follows the smaller, we cannot tell which is the male and which is the female.
