The Cloudless Sulphur, Phoebis sennae is a bright yellow butterfly that is frequently found in southern United States, but can be found west to the Rockies and north to Canada, and even the Caribbean and South America. The genus Phoebis refers to the Greek god Apollo and infers “bright and pure,” while sennae refers to the host plant (Fabaceae, which are legumes). Phoebis sennae, like the Monarch butterfly also migrates south in the winter to Florida to escape the cold weather. The species has declined since the 1980s, and is thought to be linked to increased herbicide use. For more information check out this Featured Creatures website.
Most specimens (but not all) have two images per moth, dorsal and ventral. The reason for this is because there sometimes is critical information on the back of labels. So be sure to check both images! While checking both images, look at the amazing shapes and minute coloration of the moth. Thank you so much for your help!
Transcription generally follows standard Notes from Nature protocols. Please be sure to write all pertinent information to the corresponding field. Please type all label data exactly as written on the label. The one field that is unique to McGuire is sampling protocol (collection method). This is how the person collected the specimen. It could be net, but often with moths it is some type of trap or light. Please write verbatim what is on the label.
