Homalictus bees - homalictus sp.

Although very small (most less than 8 mm long), the glittering Homalictus Bees come in a dazzling array of colours. ‘Golden blue’, ‘coppery red’ and ‘green tinged with purple, red or gold’ are just a few of the colours listed by scientists. 

Homalictus Bees dig intricate branching nests in the ground. Many females may live together in each nest, taking turns to guard the narrow nest entrance. One nest  was found to be occupied by over 160 females!
