The spotted lanternfly's life cycle is often centered on its preferred host, Ailanthus altissima, but L. delicatula can associate with more than 173 plants. Early life stages of the spotted lanternfly are characterized by spotted black and white nymphs that develop a red pigmentation and wings as they mature. Early life instars have a large ...
Owl butterflies are very large, 65–200 mm (2.6–7.9 in), and fly only a few meters at a time, so avian predators have little difficulty in following them to their settling place. However, the butterflies preferentially fly in dusk, when few avian predators are around. [ 1 ]
The lanternflies also excrete a sticky, sugary substance called honeydew that can attract other insects and cause mold to grow on the plants and trees they target.

Owls are divided into two families: the true (or typical) owl family, Strigidae, and the barn owl and bay owl family, Tytonidae.

[13] [40]: 84 Bright blues, greens, reds, and iridescence are usually created not by pigments but through the microstructure of the scales.
