Found it on my tomato plant. I'd seen them before in sizes up to 4-5 cm. They eat the tomato leaves like crazy. And (naturally) poo a lot. Some black granade like aggregates. Once grown they molt into a moth that I saw a few days ago. And now my tomato plants are again riddled with these buggers.
This photo was done with the help of a stereoscope. The grid squares are 4mm inside, and 5mm outside the lines. So this juvenile has about 1cm.
I'd love to ID them. Any advise on how to control them without pesticides is also welcome.
If I let them grow, I'm sure I can send you a good bag. XD
