Not the greatest of pics, but maybe you can still help. old, old phone camera. :(
Maybe I can get a better pic if you guys/girls need one.
plants affected: brassicas
another bad one.
Yes, it's almost impossible to see with any certainty, but when you say brassica at this time of year, I think aphids. Often those on brassicas are the soft, grey ones. Aphis on plants don't move around much. You can stand and look at them and not see any activity but that doesn't mean the little critters done have legs and done move.

Aphids are common on brassicas and if present are quite easily controlled with sharp streams of water that wash them off the plants. Aphids on brassicas are usually a grayish/green in color.

Yep. That's what I thought also and after seeing pics, it's confirmed.
Thanks calliope and kimmsr.
By the way, these are eggs and not adults, correct? Is neem not effective on the EGGS of aphids?
No chance of a decent picture? One thing for absolute certain...they aren't aphid eggs. You should be able to see 6 legs and a long pair of antennae. They even move around, albeit slowly.
Aphids are born alive in their juvenile stages. If you gently lift and dislodge one and look at it under a hand lens, you will see the whole nine yard, including legs.
