In May large numbers of moth and butterfly eggs hatch.
These tiny caterpillars feast on the buds and new leaves of a wide variety of plants.
As well as these young caterpillars there are also species which have overwintered and may already be fully grown and soon be pupating.
These are some of the most commonly found caterpillars in May. Some will also have featured in the March and April caterpillar update.
