Zebra Longwings live an unusually long life, and can survive more than a month as adults rather than the typical 1–2 weeks as most butterflies. This is partly because they ingest pollen as well as nectar, giving the Longwings an extra source of protein.

Our state butterfly, Zebra Longwing, or Zebra Heliconian, is named for its striped wing pattern. This coloration is a warning to predators that the butterfly is toxic. Their toxic nature comes from chemicals called cyanogenic glycosides that taste bitter, and if ingested, are bad for one’s health. The nasty chemicals derived from the hostplant – the Passion Vine – protect caterpillars as well. The caterpillars are white with black spots and black spines and are conspicuous, because they too signal to predators, “Don’t eat me!” Caterpillars pupate on or near hostplants and the chrysalis looks like a dry leaf and is hard to find.

Zebra Longwings are found from Peru in South America and as far north as Texas and Florida. Butterflies may move from Mexico to Texas, following changes in temperature. In North Florida, populations may freeze out during an unusually cold winter. In that case, the distribution of Zebra Longwings in the state may contract to just South Florida, and it takes several years for the species to repopulate the northern part of the state, including Gainesville.

Unlike most other butterflies, male Zebra Longwings mate with a female before the female has a chance to emerge from its chrysalis. So, even though the chrysalis is hard to find, male butterflies manage to do so. Once males find a chrysalis, they visit it repeatedly and perch on it. This begins way before mating happens. If a male senses through chemicals that the pupa is that of a female, it continues to return to it more and more frequently. Intruding males are fended off by an opening of the wings. Mating happens for several hours, and the female emerges during this process to expand her wings. No other males attempt to mate with this female after it has been mated, because during mating the male repellent is transferred from him to her. Despite the fact that the butterfly is one of the most common in the state of Florida, these details of its reproductive biology have been described only recently by the Florida Museum’s scientist, Dr. Andrei Sourakov.

Zebra Longwing is the only representative of this genus in the United States and is a fascinating model for education and research. It is also easy to attract to your garden: simply plant some Passion Vines and nectar plants, and swarms of these beautiful butterflies will populate your garden.
