description Hornet Moth Overview

The Hornet Moth (Sesia apiformis) is a species of clearwing moth belonging to the family Sesiidae, native to Europe and the Palearctic realm. It is a textbook example of Batesian mimicry, having evolved physical characteristics and behaviors that closely resemble those of stinging hornets to deter predators. Unlike typical moths, its wings are partially devoid of scales, resulting in transparent sections that enhance its wasp-like appearance. The larvae of this species are wood-borers that primarily develop inside the trunks of poplar and willow trees over a multi-year cycle before emerging as adults.

help Hornet Moth FAQ

Why does the Hornet Moth look like a wasp?

The Hornet Moth (Sesia apiformis) uses a survival strategy called Batesian mimicry, evolving to perfectly resemble a stinging hornet. This tricks predators, like birds, into avoiding the moth even though it has no stinger and is completely harmless.

Where can you typically find Hornet Moths in the wild?

The Hornet Moth is native to Europe and parts of the Palearctic region. They are most commonly spotted resting on the trunks of willow and poplar trees, which serve as the primary food source for their larvae.

How do you tell the difference between a Hornet Moth and a real hornet?

A Hornet Moth has a completely black head and thorax, whereas a true hornet has a reddish-brown head and thorax. Additionally, the moth lacks the distinct "wasp waist" found on stinging hornets and possesses fuzzy, feathery antennae.

Are Hornet Moths considered an invasive pest anywhere in the world?

Yes, the Hornet Moth is considered a minor forestry pest in parts of North America where it has been accidentally introduced. The larvae bore into the trunks of poplar and willow trees, which can cause significant damage to urban landscaping.
