Protoparce quinquemaculata ab. wirti Schaus, 1927
Explanation of Names
Latin quinque- "five" + maculata- "spotted"
Adult: Similar to Carolina Sphinx, but has five pairs of spots on abdomen, not six. Zig-zag lines on hindwing are sharp, separated by white.
: The caterpillar has eight v-shaped stripes rather than the seven diagonal stripes of the similar Tobacco Hornworm (larva of Carolina Sphinx). The horn is also straight and blue-black rather than orange, yellow red. Unfortunately many images of these caterpillars found on the internet are misidentified. See National Gardening Association
website for correctly identified image of larva.
Includes eastern North America. More common in southern states, especially along the Gulf Coast.
Larvae feed on tomato, tobacco, and relatives (Solanaceae).
Adults take nectar from flowers including Japanese honeysuckle (Lonicera japonica), petunia (Petunia hybrida), bouncing bet (Saponaria officinalis), tobacco (Nicotiana), and phlox (Phlox).
Pupates in soil and overwinters at that stage.
Caterpillars are sometimes a pest of cultivated plants.
Adults fly at dusk.
