At the Sanctuary, we have a small community of Golden Digger Wasps seen in our gardens. They are large, bright orange, and quite eye-catching.
Luckily for us, these wasps are non-aggressive and simply enjoy visiting blooming flowers to get some sugary, nutrient-rich nectar to fuel their hunt for prey. These wasps have a short lifecycle, only living for a few weeks as adults, where their main goal is to mate, dig a large, multi-room burrow to lay eggs, and hunt food for their larvae.
In this case, their main food source for their larvae is grasshoppers and katydids. As adults, the male wasps gather outside of closed-off burrows where females may emerge in the late summer and fight for mating rights with the female.
Once the female has successfully mated, she begins her life's purpose, protecting her eggs from fall until summer.
Only females are equipped with a stinger, which they use ONLY to paralyze prey. She creates a special venom that only stuns her prey, so she can take it back to her burrow, place it in one of the many chambers, and lay an egg on top of it.
The prey is paralyzed in order to keep the food source from rotting while the larvae develop into an adult, which can take up to 2 weeks.
The wasps are also accidental pollinators! While visiting flowers for food and energy, they accidentally pick up pollen. They have distinctive golden hairs along their head and thorax that accidentally gather pollen and transfer it to other plants.
Due to their clumsy nature and large, strong bodies, they don't carry much pollen, but are able to knock it off easily onto plants adjacent to them. In particular, they are much better at reaching the pollen of plants like milkweed, which have special large packages of pollen. These large and strong wasps are able to tear into the flower further to reach these packages and break them apart, better than butterflies can.
So next time you see them in your garden visiting your flowers, its ok to take a closer look from a safe distance and observe their behavior. They are fierce, yet peaceful creatures and extremely beneficial for flowers and soil!
