The Colorado potato beetle is the gardeners worst nightmare, as it voraciously gobbles up the leaves of potato, tomato and aubergines plants! 25,000 species of this beetle exist.

These insects belong to the leaf beetle family and can be recognized by the presence of 10 yellow and 10 black stripes on their curved backs.

These colors tend to drive away predators.  Their wings, which allow them to fly,  are hidden beneath their elytrons.  Between 1 cm. and 2cms. in length, this insect has two small club-like antennae.  Its chest and its head are browny-black.

The Colorado beetle originates from North America, as its name suggests.  For centuries, it lived isolated in the Rocky Mountains, where it fed on a wild species of the potato plant.  But with the expansion of this plant around the 1850’s, the beetle gradually colonized the American continent.  Within 25 years, it spread rapidly throughout all the eastern regions of America.  This invasion was so dense that it shocked the European authorities.
