Adult flies have six legs.

Quick Scoop: How many legs does a fly have?

Flies are insects, and like all true insects they have three pairs of legs, for a total of six legs attached to the thorax (the middle body section).

Each of the three thoracic segments (prothorax, mesothorax, metathorax) carries one pair of legs, which is why you always end up with six, not four or eight.

Those legs are multi‑segmented (coxa, trochanter, femur, tibia, tarsus), and the tips have claws and sticky pads (pulvilli) that help flies walk on walls and ceilings and even “taste” surfaces.

So if you’re ever in a quiz or forum debate about “fly legs how many,” the correct answer is: six legs, three pairs, all on the thorax. ✅

TL;DR: Flies have 6 legs (3 pairs), not 4 or 8.
