I have a large brick patio behind my house. In the last couple of days I have seen about a dozen little caterpillars trying to cross it. The heat made me think that they would not make it. I started pouring a little water in the grout joints in front of them. A couple of them got stepped on, so I got a piece of junk mail thin cardboard and let the rest of them crawl up. Took them to planters and dumped them.
They are about 3/4 inch long with a wider front half than back. White stripe across the middle. Anybody have an idea what they may be? There are Monarchs flying around, so that was my first thought. I tried to search on line but could not find a picture. I know, this is not news. Just a question for a person with knowledge.
