Snowberry clearwing vs Hummingbird clearwing
These two are easy to mix up. Here's how to tell a snowberry clearwing from a hummingbird clearwing, and whether either one bites or stings.

Snowberry clearwing
Hemaris diffinis

Hummingbird clearwing
Hemaris thysbe
≠The key differences
H. thysbe is very similar but has an olive-green thorax, a dark red-brown abdomen with yellowish patches, and pale (yellowish) legs; H. diffinis has black legs and a black stripe running from the eye along the side of the thorax.
Very similar and often confused; H. diffinis has black legs, a black band across the abdomen and a more yellow-and-black 'bumblebee' look, while H. thysbe has pale legs and an olive-green thorax with a burgundy abdominal band.

🔍How to spot a snowberry clearwing
- Clear windows on both forewings and hindwings: large transparent panels lacking scales
- Diurnal, fast hovering flight like a small hummingbird while feeding at flowers
- Fuzzy, stout body with a golden-yellow thorax, black-and-yellow banded abdomen and black legs
- Thickened, hooked antennae tips typical of sphinx moths
🔍How to spot a hummingbird clearwing
- Look for a moth that hovers at flowers like a hummingbird and extends a long proboscis while feeding
- Check for partly transparent wing 'windows' where scales are missing, with colored margins on the wings
- Note the olive-green thorax, burgundy band on the abdomen and pale legs
- Caterpillars are green with a pale line along each side and a horn near the rear
