Agree with LMRR, some of those first ones do look rather scary! The last four of the first lot could even be modern art, some of which are scary, too. Great shots of the mealworm, the second one is really interesting.
I have a small chunk of Amerthyst that looked interesting under the scope today The first two pictures are at x20 magnification the last is at x400 magnifications robert
Plant stems cut across and magnified a few times. This first two are purple sprouting. Second two are a small potato stem. robert
If you see any of these on the underside of your brassicas. Then I do believe you have the pleasure of white cabbage butterfly to help you consume your veg! robert
