Snowberry Clearwing

Fascinating facts about the Snowberry Clearwing

• A moth that hovers like a hummingbird and drinks nectar in broad daylight — the snowberry clearwing has transparent wings and a body shape so bird-like that even seasoned naturalists do a double-take. Unlike most moths, which are nocturnal, this one works the same daylight shift as actual hummingbirds, visiting 500+ flowers in a single foraging session. It's a case of convergent evolution: two completely unrelated animals solving the same problem (hovering flight, high-energy diet) with nearly identical blueprints.
• Its wings are missing scales — the very thing that gives most moths their fuzzy texture and colour. Instead, the snowberry clearwing has clear, scaled-free patches that look like glass windows, revealing the veins and muscle beneath. This transparency is thought to reduce weight and wind resistance during hover-feeding, letting the moth hang motionless in front of flowers for up to 3 seconds at a time.
• The caterpillar spends up to 10 months buried in soil as a pupa, longer than almost any other North American moth — a survival strategy for unpredictable spring weather. When the adult finally emerges, it has perhaps 6 weeks to find a mate and lay eggs before it dies, making every foraging trip a race against the calendar.
• Its proboscis — the needle-like drinking tube — can be as long as its entire body and coils up like a garden hose when not in use. It unrolls in less than a second to probe deep into tubular flowers like snowberry (its namesake), honeysuckle, and dwarf bearded-tongue, reaching nectar sources that hummingbirds can't access.
• Adult snowberry clearwings don't eat for the first few hours after emergence from the pupa, even though they're fuelled by stored energy reserves that last only weeks. This narrow window — waiting for wings to harden while the body burns precious fuel — reveals how precarious life is for an insect that must find, court, and breed within a single season in the temperate forest edge.
