There are 46 ladybird species now found in Britain but only 26 are easily recognisable as ladybirds. Many are plant-feeders but other are predators of other insects; while others are fungus-feeders, or re-cycle decaying animal or plant remains, including dung. Ladybirds are very useful insects, because many species prey on common garden pests like aphids.
Earwigs (Dermaptera) as these have short wing cases and chewing mouthparts but they also have a pair of long ‘pincers’ at the end of the abdomen. They could also be confused with True bugs but True bugs have only partly hardened fore wings and sucking, needle-like mouthparts.
