We have always wondered what these neat looking bugs were called! they almost look like their shiney and rainbow color from far back but on closer inspection they are the color of a firefly, except they are longer and skinnier looking, and a bit smaller in overall size.

I believe these are also known as Ermine Moths.

The Ailanthus Webworm Moths are usually considered only minor pests - when in their larval form (caterpillar) .. especially in plant nurseries.

It's reported that they rarely do any serious damage.

Many times, folks have a tendency to forget that these guys are also valuable pollinators while in their moth form!
