Beginner Gardening: Are these seeds?, 1 by emblue

I had these posted on the insect forum, and someone thought maybe they were seeds instead of pests -- are these familiar to anyone?

Photos taken just this afternoon in Southeastern PA (Bucks County). The petunias all have them -- 4 planters full. The flowers keep getting holes/dying off -- nothing seems to be crawling around/moving, but there are lots of these small "things" all over. In 3 of the 4 planters, they're in with celosia. In the 4th, they're in with another flower (can't remember the name but photo included at my original post here: http://davesgarden.com/community/forums/t/894907/ ).

The 3 planters are up on the fence (the 4th is down on a table). I've been keeping the weeds down in the yard (used to let them grow big big because they were pretty and the birds liked the growth but they were cleared out this spring), so nothing's bloomed in the immediate area -- but I live in a condo development and my unit's right by protected wetland with a stream and lots of trees/bushes/etc. -- all different growth within 20-40 feet.

I have vegetable plants in containers in the yard, too -- bush beans, snow peas, carrots, tomatoes, cucumbers, mint, basil, cilantro, mesclun, pimentos -- nothing's really done yet, but the bush beans and snow peas are probably closest to done.

Familiar as seeds? They're tiny -- about the size of poppy seed maybe?

Two other photos also at the original post: http://davesgarden.com/community/forums/t/894907/
