This beetle like insect appeared yesterday on my block wall, I went to the other side of the wall and they were in 100’s in a vacant lot with scrub desert brush climbing the wall. Temps were 95ish. They are at least an inch long and very colorful. What is it and is it an issue in my garden?

Hi Pat Z.,
This Iron Cross Blister Beetle in the genus
 Tegrodera is one of the most distinctive looking North American Beetles.  The bright colors of the Iron Cross Blister Beetles are aposomatic, and provide a warning that the beetles are capable of releasing a blistering agent known as cantharadin from their joints, so they should be handled with caution.

Thank you so much, I could not find it anywhere with a picture
