A dark-bodied, heat-tolerant bee found in arid inland Australia. It forages during the hottest parts of the day when most other bees are inactive.

💡

Did You Know?

It can remain active in ambient temperatures exceeding 40 degrees Celsius that would ground most other bee species.

Columbine Sawfly

A small, dark sawfly whose pale green larvae feed on the leaves of columbine plants. Larvae can cause significant damage in flower gardens.

💡

Larvae feed from the leaf edges inward and can reduce a columbine plant to bare stems and leaf ribs within days.
