Curator’s Choice

The Madagascan Sunset Moth, Chrysiridia rhipheus, was initially described as a butterfly, due to its brilliant colors. However, it lacks the clubbed antennae characteristic of butterflies and therefore is indeed a moth! These moths, which are only found on the island of Madagascar, are toxic to predators when consumed, and advertise their toxicity with their bright colors, similar to the Monarch butterflies found in California. Like Monarchs, sunset moths migrate, but not in response to weather. Instead, as their caterpillars feed, the plants they consume increase in toxicity, and eventually the plants become too toxic to eat. When this happens, the moths migrate to a new region, where the plants are more palatable. This specimen is one of over 350,000 insects preserved in the Entomology Collections at Santa Barbara Museum of Natural History. Inspired to get up close with more winged wonders? The Museum’s Butterflies Alive! exhibit runs through September 1.

Curator’s Choice is a new weekly column from the Santa Barbara Museum of Natural History, offering Montecito Journal readers a glimpse into the remarkable stories behind special items in our collections. With over 3.5 million specimens, artifacts, and documents, the Museum preserves the natural and cultural heritage of our region while promoting scientific literacy and a deeper connection to the natural world. This mission is made possible through the generosity of our community: 350 volunteers contribute more than 17,000 hours annually, supporters donate $3 million each year, and a growing number of legacy donors are securing the future of our cherished scientific and educational institution by adding the Museum to their will.
