Entomology (Study of Bugs)/Information Please

I saw this insect in a social media channel and would like to know the name and where it is from. Thank you!

Dear Israel - This is a male moth in the subfamily Arctiinae (Lepidoptera: Erebidae) with its coremata (eversible scent gland) on display. The 'scent' (actually a sex pheromone) is dispersed by the male for the purpose of attracting potential mates. See http://tinyurl.com/kjlezuz for more information, including a short video clip. Moths of this type are very widespread; I would have no way of knowing exactly where this particular specimen originated.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
