Bug ID?
« on: December 10, 2016, 01:34:07 PM »
Just like last year I have hundreds of these in my garden and they clearly like it as they are mating all of the place. They're on every plant, seem particularly enamoured of the cucumbers and beans though. I wonder if they are causing the damage pictured.

I think it's a Mirid bug of some kind... but a pest or a predator? I've seen it mainly feeding on pollen but it's on the cucumber leaves a lot. I don't want to spray because I believe lacewings etc. are keeping the aphids and whitefly under control for the moment and I don't want to kill them too.

They are small, maybe 5mm at the biggest.

I believe it is the "Rutherglen bug". It's on everything from my raspberry canes to potatoes. I've held off spraying but I think I'll do a big oil spray, as whitefly are starting to build up too. Hopefully I don't kill too many ladybirds or lacewings.

Eco-Oil didn't kill them but Natrasoap is lethal. I'm not convinced Natrasoap is safe for most beneficials though, and it leaves stains on concrete and a residue that doesn't easily wash off edible crops so I'll try to restrict it to fruiting crops.

looks like what we call harlequin bug

simple kitchen detergent in a spray bottle will stop them  , it clogs there breathing and they die
also if you can find a nest  boiling water works wonders

Description and photos match the Rutherglen bug as mentioned. I get the related species quite often, the harlequin bug. Not sure why but they are all gone. Lots of the bigger predatory bugs so perhaps the balance has been tipped in their favour. If only the same occurred with the snails.
