We get quite a lot of Black Witch moths out here in south Texas. Considering their abundance at times I have yet to find any caterpillars. The eaves of the ranch house are painted dark brown and at times I can walk around the house and count a dozen or more Black Witch moths snoozing during the day.
We like to joke and call the Black Witch moth males " Warlocks"
I put out butterfly brew during the day for the fruit feasters (butterflies of the brushfoot family) and the BW moth is usually a frequent night time visitor to the tray.
