White-lined Sphinx
This powerful moth can look like a hummingbird at dusk, hovering precisely while its long tongue reaches deep tubular flowers.
Artwork inspired by Terry Redlin
Larvae vary from green to nearly black but usually carry lengthwise spots and a harmless rear horn. Population surges follow favorable rains, when caterpillars may cross roads in great numbers before burrowing to pupate.
Wait beside evening primrose or other tubular blooms instead of chasing flight. Use dim red light, never handle a feeding moth, and move road-crossing caterpillars only when immediate traffic danger makes intervention necessary.

A close field reading of White-lined Sphinx
- Recognition
- Large fast moth with a bold white forewing stripe and pink-banded hindwings
- Habitat
- Concentrate on prairie, gardens, badlands washes, roadsides, and open country.
- Seasonal context
- Treat the first impression as a lead, not a conclusion. Compare wing surfaces, antennae, body pattern, scale, and associated plants before recording White-lined Sphinx.
- Evidence to record
- Warm evenings from late spring into autumn are best. Watch flowers for hovering moths, then record both wing surfaces, body pattern, and nectar plant.
Good to know
A close image of White-lined Sphinx is not automatically decisive: habitat, timing, full structure, and the alternative species considered should remain part of the record.
