What would dirt daubers eat if dirt was gone?

If dirt was gone, dirt daubers, which primarily feed on Spiders and other small insects, would likely adapt their diet to include alternative protein sources. They might hunt for other insects or scavenging opportunities, such as feeding on decaying organic matter or seeking out nectar from flowers. However, the absence of dirt would also disrupt their nesting habits, potentially leading to population declines. In a broader ecological context, their role in controlling insect populations would be significantly altered.
