Flying Burrowing Insect?
Wed, Mar 25, 2009 at 5:25 PM
Have recently found this insect making nests in the ground in our backyard. I have never seen this insect before and was wondering if you site could help me identify them. They look to be a cross between a small fly and a wasp but they are only about 5mm long. You can see in one of the photos the holes in the ground where they are burrowing. There are at least 10-15 different holes scattered around where they are coming in and out. They are not any trouble but just wondering what they might be so any help would be fantastic.

We believe you have a colony of Homalictus Bees. According to the Which Native Bees Live in Your Area website: “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! ” and “With glints of aqua blue, golden green and orange, these Homalictus bees make a stunning sight! Just 5 mm long , these bees are tiny living gems.”
