Notes

The Carolina Sphinx is commonly called the Tobacco Hornworm but is much more commonly found on tomatoes then the closely related Five-spotted Hawkmoth (commonly called the Tomato Hornworm). These caterpillars are common hosts for parasitic wasps that lay their eggs inside the caterpillar and emerge after the complete their metamorphosis, thus killing the caterpillar.

Conservation Status

• Global status: G5 (secure)
• National status: N5 (secure)
• Indiana status: NR (not ranked)

Floral Associates

Carolina Sphinx caterpillars hosts on a variety of low-growing plants, many of which are common in gardens and agricultural production, especially species in the Solanaceae Family which includes garden tomatoes. This preference makes them somewhat of a pest to farmers and gardeners.

Adult use their long proboscis to feed on nectar from various flowers.
