Before I go any further, I must say it’s raining! When it rains to any significant extent once the hot weather starts, it’s worth mentioning. We will have some happy plants, and I set some seat cushions out to get cleaned, too (it’s free!).
One thing the rain is washing away from those cushions will be mud dauber nests. We always have some here (ours are black-and-yellow mud daubers, Sceliphron caementarium), but this year they are especially abundant. I have always enjoyed watching these guys and find the places they make nests pretty funny sometimes. You never know where one will show up, like on a shovel, in the lawn mower, etc. They were all over those seat cushions, too. They use such nice, brown mud. Quite the construction workers!
