Entomology (Study of Bugs)/Yellow-Gold Colored Beetle

Ran across this small beetle on my pool screen.  It appears to be about 3/16" long.  The antenna added confusion to making the ID.  I figured it might be a goldsmith beetle "Gold Bug", then maybe a Tortoise Beetle.  Can you provide the common name and the scientific name.  Thanks

Hi, Ralph:

Definitely a leaf beetle, family Chrysomelidae.  *Might* be Colaspis , but there are many leaf beetles that look like this, at least superficially.

There is also a great deal of variability within a single species in many cases, which only adds to the confusion.

The "Goldsmith Beetle" is a much, much larger and more robust insect.

Have a great weekend!

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
