Two bugs, Harlequin bug - Murgantia histronica and Painted bug - Bagrada hilaris, are often confused.
They are both bugs in the Pentatomidae Family (Stink bugs a.k.a Shield bugs); they have similar coloration and markings; they are both introduced to our area; they are often found in the same habitat and sometimes on the same plants.
Harleguin bugs are the larger species. They have been in our area for a long time and are sometimes thought to be a native species. They are native to Mexico and Central America. Look for Bladderpod, Isomeris arborea, and there is a very good chance you will see them.
Painted bugs are much smaller. Even if people are familiar with Harlequin bugs, I've heard people incorrectly say they are the babies. That may be because the painted bug is new to the area and few people have seen it before. Originally from Africa, they were first found in Los Angeles County in 2008. Since then they seem to be quite numerous and widespread.
Look at the photos below to help distinguish them.
