They are characterised by long thread-like antennae and include quite a few large species. We find no external structural features that indicate that this larva lives with ants, as do many other members of the carabid beetle subfamily Paussinae. Lamellate antennae, size quite variable. With distinct prolegs .....26. 2.5a, ... Coleoptera 25¢. Early instar larvae are very small and difficult to identify, but third and fourth instar larvae, particularly of the larger ladybird species, may be identified in the field. The second half of the Handbook is a systematic survey of the biology of each family. On the one hand, it is a remarkable work that has involved many individuals, some of whom are no longer alive, and a great deal of specialist input. Start- The first decision along the identification path is whether or not the larva has segmented thoracic legs.

Larvae eat, grow and molt. This guide is just another source to help you name a beetle. Summaries are given of general larval morphology, specialised biological aspects (such as hypermetamorphosis and parasitism), habitats and behaviour as aids to identification, pest species and biological control, and collecting, preservation and rearing.A detailed preliminary key, with 33 couplets, helps users distinguish Coleoptera larvae from other immature insects. Not all elmid genera known to occur in French Guiana are known in the larval stage. Beetles that can cause problems in gardens and/or in agriculture include: wood-borers such as longicorn beetle larvae (Cerambycidae) as well as beetles that may attack plant leaves, such as leaf beetles (Chrysomelidae), or roots, such as Christmas beetle (Scarabaeidae, genus Anoplognathus) and chafer grubs (Scarabaeidae, subfamily Melolonthinae).
