I'm a new gardener with very little experience. Something is attacking my leafy greens & cucumbers! I can find no insects on the leaves each time I search although I did see what looked like a yellow ladybug elsewhere in the yard & may have been a squash beetle? Help! I've attached pics of beets, chard, kale, & cuc leaves.

Welcome!

The beets and chard appear to have leafminers, look inside the damaged areas for larvae feeding inside them. For the kale look underneath the leaves for green caterpillars, they may be small. I'm not sure about the cucumber problem, there are a few things it could be.

I agree
Chard. Could also be slugs or snails.
Kale. Could also be cabbage loopers. Also, green worms, that blend in perfectly, with the white veins on top of leaves.
Cucumbers !!! That yellow lady bug, that, you saw, was probably a cucumber beatle. They carry a blight virus. They attack other veges, also. They lay eggs at base of plant. So spray base of plants also. You may want to yank cucks out. And start some other place. Blight virus lives in ground, for a few years. I say ! Use snail pellets and dust or spray with DE.
Anything i say, could be misrepresented, or wrong.

The cucumbers seem to have spots rather than holes. A cucumber beetle would be eating the leaf but the leaves look intact other than around the edges. The edges look "worn" rather than chewed. If it's an insect, I would suspect a piercing-sucking insect rather than a chewer, or the start of a disease or environmental problem.

Nobody's mentioned this, but doesn't most of that leaf damage look like fertilizer burn, or sun scald?

For the cukes it did cross my mind, I was lumping sun or salts in with "environmental problem". Brown leaf edges could also be a nutritional/moisture deficiency issue. I don't think any of those would account for the yellow spots though. Of course there may be more than one thing going on at the same time.

Pictures of cucumber diseases causing spots, there are several different ones, some fungal some bacterial:

The chard/beet problem looks more like leafminer to me, compare with this image. It should be easy to confirm if the critter is still in the mines but it also could have already left.

Cucumber Beatles dont damage plants much. Larva eat roots, not much damage, but, they carry a blight, virus, wilt, or something like that. That cant be cured.
Most likely suspect. Where there's one cucumber beatle There are are more.
I did say LIKELY ! Didn't i !!!

Good point, Philip, but we don't know it was a cucumber beetle. Wsdoin said it might have been a squash beetle (there is a yellow one with black spots but I haven't checked its range). On the other hand since it looked like a yellow ladybug, it might have been a......yellow ladybug Sticking tongue out There's one that occurs in Utah and eats aphids. So if it's a cucumber beetle there will be more and maybe wsdoin can post a picture so we can identify it. Wouldn't want to be murdering a yellow-aphid-eating-ladybug Big Grin

Use diatomaceous earth for leaf miners, snails, slugs, hornworms, cabbage worms which is what your kale fell victim to, it is excellent for etc. Within 2 days all crawling insects will be gone; just have to be careful if you have a lot of worms in your garden, harms them too. The beets don't suffer too much from leafminers just sore on the eyes.

Thank you'd nuch all of you! So, so helpful. Leaf miners appear to absolutely be the prob with the beets & chard. Kale is caterpillar...identified some eggs finally on the back of one. Cucs is still unknown. Definitely not cuc beetles. Still unknown whether the yellow ladybug was indeed a ladybug & not a squash beetle, but would definitely have been a squash beetle as opposed to cuc beetle for sure. I'm thinking the cucs are suffering more from something environmental. Possibly sun scortch, but not sure. I'll post more pics of the cucs & continue examining. The only thing added to my soil has been Replenish brand compost.
