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.
Comparison of hummingbird moths and hummingbirds:
Feature | Hummingbird Moth | Hummingbird |
---|---|---|
Size | 1½ to 2¼ inch wingspan | 3 to 5 inches in length |
Body color | Greenish-yellow or tan with reddish band | Various bright, iridescent colors |
Wings | Scale-covered, some species have clearwing | Feathered |
Food source | Nectar | Nectar, insects, and spiders |
Overall, the life cycle of a hummingbird moth includes stages of egg, caterpillar, pupa, and adult, each with distinct features and roles. Utilizing host plants and hovering to feed on nectar, these fascinating insects are important pollinators in their ecosystems.

I think I also saw this moth between October 16 and 21 in Iwate prefecture (northern Honshu), Japan. At first I thought it was a hummingbird, but a bird book revealed no hummers in Japan. The wings were a rust colour and the proboscis was long and curved. It darted among the golden nasturtiums with a distinct humming sound. It was in the same location for several days, always when it was sunny and calm. Unfortunately I did not have my camera with me. Thanks for the ID.
Hello! Are then any previous sightings of these in Australia? I think I saw one today in Grenfell in central west NSW. My friend and I were extremely perplexed as to what it was, and it took quite a few google image searches before I recognised what we had seen. Is is possible its a different species?
Also…I just found another moth that looks very similar from America – the snowberry clearwing Moth. What are the similarities and differences between these two? The one I saw today seemed extremely similar, but it did seem to be smoother on the top half, while distinctly fluffy on the bottom half.
There are many related species in Australia. See Butterfly House for Australian Sphingiids.
