ID of landscape pest
I live just south of Tampa, FL. I noticed that I have these small, flat black disc type pests. I'm not sure what they are. Then I noticed I had clusters of what appear to be egg pods throughout my yard. It looks like each of the "eggs" opens with several of these black flat disc-type pests. I thought they might be a type of scale, but can't find anywhere showing that scale "hatches" in pods like these. The pests are on Areca palms, hibiscus, agapanthus, and even migrating on to the lanai screen and house stucco. Any ideas what they are? Many thanks, in advance.
