Longhorn beetles Siklased Cerambycidae
Longhorn beetles are beetles with a narrow body and long antennae. Many longhorn beetles have colourful outer or cover wings (elytra), others have a tree bark coloured pattern. The imagos or fully developed insects we meet in summer on the flowers and leaves of plants and on tree trunks. The larvae of longhorn beetles develop in wood. Because wood is poor in nutrients the development may last several years. As a result some longhorn beetles are forest pests. Longhorn beetle species prefer one or some specific kinds of trees.
