As midges start to fly, in mornings and evenings, so a great many poor ponies will start to suffer distressing signs and symptoms. Native pony breeds are particularly susceptible. Severe itchiness (pruritus), damage to the coat and skin sores (esp. mane, withers, rump and tail) are common signs. Happily, much can be done for a good proportion of these.
