Hummingbird moths

In Quebec, this species produces two generations each year, except in northern regions, where there is only one.

Females from the first generation are active from spring to early summer. They lay their eggs on several host plants, including viburnums, hawthorns, honeysuckles, and trees or shrubs in the Prunus genus.

Small caterpillars hatch from the eggs and feed on the leaves of these plants. Once fully grown, the caterpillars hide in the leaf litter before becoming brownish chrysalises.

The moths that emerge from these chrysalises make up the second generation. They can be seen on the wing from mid-summer until September. In turn, they lay eggs that will develop into caterpillars and then chrysalises. These new chrysalises overwinter buried beneath the leaf litter until the following spring.
