B. Flea or leaf beetles (CHRYSOMELIDAE)

Flea beetles, also known as Leaf beetles, cover between 40,000 and 50,000 different species of small beetles which are grouped into numerous sub-families. No single characteristic defines this family of insects.

As with other beetles, the life-cycle includes larvae and adults, both of which feed on plant tissue. Many are pests of crops.

C. Alder Leaf Beetle (Agelastica alni)

This small beetle (about 7 millimetres in length) has a dark metallic blue tinge. It is found on Alder trees, but is also known to favour Beech, Hazel and Hornbeam.

The larvae of this beetle is often seen in July and August, causing much leaf damage.

This was once a rare beetle, even thought to be extinct in Britain, but there have been increasing numbers of records.
