help Hyles lineata FAQ
How do I identify a white-lined sphinx moth?
Hyles lineata has a broad pale stripe running along each brown forewing and pink bands on the hindwings. Its large body, narrow wings, and hovering flight often cause people to mistake it for a hummingbird.
What do Hyles lineata caterpillars eat?
The caterpillars feed on a wide range of plants, including evening primrose, purslane, grape, and members of the four-o'clock family. Their color varies considerably, but many have a rear horn typical of sphinx moth larvae.
Why do white-lined sphinx moths sometimes appear in huge numbers?
Rainfall can produce abundant host plants in arid regions, allowing very large caterpillar populations to develop. The resulting adults may disperse in conspicuous migratory flights across western North America.
Does Hyles lineata pollinate flowers?
Yes, adults drink nectar while hovering and can transfer pollen between long-tubed flowers. They commonly fly around dusk and use a long proboscis to reach nectar without landing.
