Fascinating Wasp Diversity

Backyard Ecology

Wasps are often portrayed as one of “the bad guys” in the insect world. But part of that common misconception comes from a lack of knowledge or understanding about wasps in general and stereotypes that don’t apply to most wasp species.

The truth is that wasps are extremely diverse and what most of us think of when we think of a “wasp” makes up only the tiniest percentage of all wasps out there. In fact, there are likely many different species of wasps that haven’t even been identified yet. And wasps play an extremely important role in the ecosystem – one that is often overlooked and not well-understood.

In this episode of the Backyard Ecology podcast, we are joined by Louis Nastasi who is a self-proclaimed ambassador for wasps. Louis is a PhD candidate at Penn State’s Frost Entomological Museum which is Penn State’s research collection of insects and other arthropods. He also founded and is one of the instructors for the Wasp ID Course, which will have its second session in January 2023.

During our conversation, Louis and I dive into the fascinating diversity of wasps, especially parasitoid wasps, and their vital roles in the ecosystem. Louis believes that a lot of the misconceptions around wasps are due to a lack of recognition of just how diverse wasps are. Contrary to popular belief, most wasps aren’t capable of stinging people and many are the size of a speck of dust.

Like with the first episode that Louis was on, our conversation takes many twists and turns. We talk a lot about parasitoid wasps and just how amazing it is that many of these parasitoid relationships developed in the first place. (One of the wasps we talk about lays its eggs in diving beetle eggs which are found underwater!) We also discuss how much we don’t know about these species and how much there is still to learn. But through it all, Louis’s passion for wasps and wasp education shines through.
