Down on the plot, the sheer number of little nibbles around the leaves of my pulses (peas and beans) and, to be honest, even my brassica seedlings, is quite disconcerting. Am I suffering from vine weevils? What's the solution?

Did you notice any vine weevil grubs as you were digging the soil? They are generally easier to spot than the adults. If they aren't already netted, birds would be my first suspects, though.

It'd be nice to get pics of bugs (insects etc, not our own bugs) for the glossary

My peas have little nibbles on them too. They are in a mini polytunnel. Had a good look round for the culprit but no luck.

I think I could get some pictures of garden pests and their damage as the season progresses. We often get nibbled leaves but it doesn't seem to affect the pea plant. It the cabbage rood fly I will have to battle with this year.

Well, I'd love piccies of anything that could potentially go in the glossary

In case I've missed something, do we need pictures of anything in the glossary? Even, for example, something like nettles? If so I can certainly provide quite a few and it's something I'm thinking of spending a little more time on.

Is there a min/max size that's good? (Please point me in the direction of another thread if I've missed it)

Nettles would be good, in fact anything, there are very few photos in there. No hard and fast rules on image size but 160w x 180h would be the maximums I reckon.

OK, I'll see what we can do. I'll concentrate on what we know and if anything special crops up run it past cab, you or others to make sure it's correct.

Didn't see any larvae, but I have found some adults. The damage doesn't look like bird damage, the damage is too small and semi-circular if that makes sense.

Are the plants under cover? Otherwise it sounds a little early for them, to me, otherwise semi-circular does sound like vine weevil, Cab. Time to send for some Nemasys! Quick!

They aren't under cover, but this is Cambridge, the city where things grow miraculously early. How good is nemasys against vine weevil?

There are several Nemasys products: one is a specific anti-VW thing. I don't use it, because we don't get a lot of trouble from the little dears, but it is reputed to be good. Have a look on the Greengardener site. And good luck!

Cheers, I'll look into it. I'd use a chemical pesticide if absolutely necessary, but it's a last resort.

If the damage looks like this, I'd suspect pea weevil

Did any of your pea seeds have tiny holes bored in them? They may have been harbouring over-wintering weevils.

Joy Larkcom recommends spraying with derris as soon as the problem appears - but if it's not too serious, the plants can grow through the first damage. But then I wouldn't save any of the pea crop as seed for next year!
