Carrot fly
The carrot fly is a small fly that gardeners know very well. Its little maggots dig into carrots and leave rusty brown tunnels in them. It finds carrots by sniffing out their smell.

How fast is it?
Fun facts
Its maggots have no legs and grow up to 1 centimetre long.
The girl flies fly very low, so a fence about 60 centimetres high around the carrots keeps them out.
Planting onions, chives or garlic next to carrots hides the carrot smell and confuses the fly.
When the maggots are at work, the carrot leaves turn rusty red and droop.
