Life Cycle of a Hummingbird Moth

Eggs

Hummingbird moths lay small, round, and greenish-white eggs on host plants, such as honeysuckle and hawthorn. The eggs are laid singly and hatch within a few days to a week, depending on the temperature.

Caterpillars

After hatching, the larvae (caterpillars) emerge, and their appearance varies depending on the species. For instance, some caterpillars display a green color with a horn-like structure at the end, while others may be brown or black. The caterpillars feed on the leaves of their host plants, growing and molting several times in the process. This stage lasts around 2-4 weeks, during which these larvae grow up to 3 inches in length.

Features of caterpillars include:

• Green or brown colors
• Horn-like structure at the end
• Feeding on host plant leaves

Pupa

Once the caterpillars have reached their full size, they pupate by forming a cocoon, either on the ground in leaf litter or by spinning a loose silk cage on the host plant. This stage lasts for approximately 2-3 weeks, after which the adult hummingbird moth emerges.

Characteristics of the pupa stage:

• Cocoon formation
• 2-3 weeks of development
• Adult moth emergence

Adult

Adult hummingbird moths are fascinating insects, notable for their hovering behavior and exceptional resemblance to hummingbirds. They have a wingspan of 1½ to 2¼ inches and display a greenish-yellow or tan body, often with a reddish-brown band across the abdomen. Their primary food source is nectar, which they acquire using their long proboscis while hovering above flowers.
