National Insect Week returns in 2022
BeetlesThis beetle belongs to the False blister beetle taxonomic family, so called because their body fluids contain Cantharidin, a poisonous defence to predators.
Thick legged flower beetles are metallic green with thin bodies of 6 to 11 mm long. The head may have a coppery or blue tinge and the wing cases (elytra) are pointed and gape apart showing the abdomen underneath Males have thick thighs (femora) and females do not.
These beetles are found on open-structured flowers such as daisies and cornflowers.
Adult thick legged flower beetles are around in Spring and Summer.
Adults emerge and can be seen on flowers in Spring and Summer, they mate and females lay their eggs in tree bark. Larvae hatch and feed in the dry stems of plants such as thistles, it is not known whether this beetle overwinters as a larva or a pupa.
These beetles feed on pollen and nectar.
When the beetles feed on the pollen and nectar of flowers, they can also transfer pollen between flowers, pollinating just as bees do.
Thick legged flower beetles occur in western and southern Europe.
