How Big Do Flies Get?

The larvae are white and about 1/8 to 1/4 inch long. Females lay eggs in organic material like garbage or decaying vegetation that is rich in food for maggots, which hatch into flies after emerging as adults. Flies can travel up to a mile or two as adults, with some reaching even 20 miles.

Do Large Flies Bite?

Flies often get a bad reputation, but not all of them transmit diseases or bite. In fact, most species are harmless. The next time you see a fly in your horse stable or on your food, know that it’s more likely to just be an annoyance rather than cause any major harm.

Do Flies Have Brains?

While they might not be the smartest creatures, flies actually do have brains. They just don’t work like ours. For example, a fly’s brain is divided into two lobes, while ours has three. The mushroom bodies in a fly’s brain are also larger in proportion to their overall brain size than in mammals. This allows them to better process smell and taste.
