While working in the yard, we couldn’t help but notice the three Great Golden Digger Wasps, Sphex ichneumoneus, that were gathering nectar from the blooming onions. Is it any wonder we have a healthy population of these wasps? There are plenty of Katydids in our garden to provide a bounteous food source for the young. According to BugGuide: “Female digs burrow almost vertically. Cells are dug radiating out from central tunnel. Larvae are provisioned with crickets, camel crickets, katydids (long-horned grasshoppers). One paralyzed prey is placed in each cell, and one egg is laid on it. One generation per year.“
These Great Golden Digger Wasps are most active in their quest for nectar. We had to be most patient in our attempts to capture these images. We lament that we were unable to get a good image of the three Great Golden Digger Wasps together.
