A large and distinctive hoverfly with three pairs of white lunules on the abdomen. It is a common visitor to flowers in gardens, meadows and waste ground in summer.
It doesn’t usually survive our winters (though this may change with global warming) and arrives as a migrant and then breeds here every summer, so numbers vary from year to year.
The larvae feed on aphids on low growing plants.
