We have several Zebra Longwing butterflies visiting our yard from time to time, but they never pause long enough for a photo. These butterflies are black in colour, with narrow yellow stripes, and have small red basal spots; I admire the pattern on their wings.
The Zebra Longwing butterfly (Heliconius charitonius) is also known as the Zebra heliconian. One of its host plants is the passion flower on which its caterpillars feed. The caterpillar are white with black spots and numerous black spines; I have never seen them.
