In this mesmerizing footage captured right in Bronx Park (Thank you, Devorah Gordin!), we are treated to an extraordinary glimpse into the behavior of wasps, specifically those from the Vespidae family. These industrious insects showcase their remarkable skills as they deftly employ their mandibles to slice a larva – likely a young moth – into smaller, more manageable sections. But what’s the purpose behind this intricate process?

Wasps are engaging in this behavior with a specific goal in mind – to provide nourishment for their developing offspring. Wasps, much like their honey bee counterparts, live in intricate social colonies, complete with a caste system comprising queens, drones, and the diligent worker bees. The queen, a fertilized female, kickstarts the colony in the spring, constructing a small nest and laying eggs that eventually hatch into larvae, pupating into workers.

In this video, adult wasps carefully disassemble the moth larvae into bite-sized pieces, each destined for their nest to feed their hungry offspring. Wasp larvae demand a substantial protein diet to flourish and mature into fully-fledged adults, which prompts these resourceful insects to prey on a variety of other insects – spiders, caterpillars, beetles, crickets, and aphids. In fact, some wasp species even serve as a natural form of pest control, keeping troublesome insects in check!

The thread-like waist of adult wasps prevents them from indulging in these delicacies themselves.

Yet, as the warm embrace of summer gradually yields to the chill of fall, the dietary preferences of adult wasps undergo a fascinating transformation. They shift from their protein-focused diet to one centered around sugars. This intriguing transition is a pivotal aspect of their life cycle, as the wasps redirect their energy towards nurturing their nest throughout the winter rather than expanding its size. During this period, you’ll observe wasps tirelessly foraging for carbohydrates – sugar! They’ll seek out nectar, fermented fruit, and yes, even your soda.

This captivating video not only sheds light on the incredible world of wasps but also reveals their precision and dedication as they meticulously prepare a juvenile moth for the benefit of their growing larvae. It’s a testament to their adaptability and survival skills in an ever-changing environment. These moments serve as a poignant reminder of the awe-inspiring complexity of the natural world, waiting to be uncovered and appreciated.
