Stable fly (Stomoxys calcitrans)
The stable fly is very similar to the house-fly in appearance except for the pointed proboscis extending forwards from the middle of the head. The larvae develop in stall dung. This species therefore occurs mainly in rural areas, where it shows a preference for human quarters in the autumn.
Both male and female stable flies bite humans and domesticated animals and suck blood. The animals may even suffer to the point that milk production and fattening rates suffer. The bites can also transmit disease germs.back
