Guide to using the caterpillar galleries
Follow the links above to go to the caterpillar galleries. When using the galleries to identify a caterpillar please be aware that the larvae of many species of insect dramatically change appearance as they grow and moult.
The images shown are of fully grown caterpillars unless stated.
Some species even have caterpillars with different colour forms within the same brood.
The photographs are of caterpillars either seen in the field or that have been reared through in order to either confirm identity or to record their transitional and variable forms.
Identifying some caterpillars solely from photos is not always easy and other information can be helpful – see help with caterpillar identification.
One of the most common caterpillar enquiries received from gardeners are those for sawflies larvae. Despite many being difficult to identify from photographs a count of the legs can often determine if they are indeed sawflies.
Some larvae may be garden pests and gardeners understandably wish to control them. In such cases identification is important as some caterpillars such as those of ladybirds and hoverflies can be extremely beneficial.
