A dozen = fourteen?

Stink bug eggs resemble little barrels. These appear nicely rounded.

Let us know who shows up.

Usually insect pests will lay their eggs on plants that are food for their young. So that's where I'd start looking first. Here's a table that lists several common insect pests of tomatoes, so maybe you can start there.

Take a look at fruitworm eggs. You'll need to find better pictures, but maybe that's what you've got.

There's this: Eggs are laid singly on foliage near the flowers or developing fruit, usually on the outer portions of the plant (Figure 1). Fruitworm eggs are about the size of a pinhead, hemispherical in shape, and slightly flattened at the top, with 12 or more distinct ridges radiating from the top. They are white when laid but develop a reddish brown ring after about 24 hours. The eggs turn black if parasitized by the tiny Trichogramma wasps, which are usually prevalent in fields not sprayed regularly with insecticides.

I'd question whether this is the problem since the eggs you photographed look larger than pinheads, but it's usually very difficult for many of us to identify insects at various stages. You're closer to them, so maybe you can definitely say yea or nay.

Could it possibly be hornworms? From the website linked:

"Female moths lay large pearl-colored eggs on the upper surface of leaves."

There's a picture near the bottom of the linked page...

looks like fruitworm eggs to me

both those guys lay solitary eggs. not in clusters.

Keep looking.

Oops wrong link! Here is the correct one

Yeah, that comes closest I think. Right color, right size, more than one egg laid at a time but still separate from each other. I guess "laid singly" (from the description of eggs for fruitworms and hornworms) actually means "solitary" as Jean mentioned. I interpreted it to mean just not in a connected egg mass.

An oyster? (sorry, couldn't resist...)

I agree with maizu that it is a hornworm egg. Here is a link to some pictures of hornworm eggs. It also shows a wasp laying her eggs inside the hornworm egg!

You must have missed the other posts. Hornworms lay their eggs singly, usually one alone per leaf and usually on the leaf's underside, not on the top in groups as is shown in the OP's picture.

Your picture shows a solitary egg, and yes, it's a hornworm egg.

FWIW, you are correct that some stink bugs have barrel-shaped eggs. Green stink bugs do. They look like they have circular lids.

The brown stink bug has . That looks like what the OP photographed.

The southern green stinkbug has what's referred to as . Maybe that's their shape but it's hard to tell. All the pictures I've seen seem to show that the shape of the egg mass is almost geometrical, with two straight sides, which ought to be a good identifier.

And

(Wish they'd make up their minds!)

From this link: Egg - When first laid, the barrel-shaped eggs of the green stink bug are yellow to green, later turning pink to gray. Eggs of the green stink bug measure 1.4 x 1.2 mm. The white, kettle-shaped eggs of the brown stink bug are slightly smaller than those of the green stink bug. The creamy, cylindrical eggs of the southern green stink bug measure 1.0 by 0.75 mm and develop a pinkish hue before hatching.

I have fruitworms every year. They lay in clusters. maybe they didn't get the memo.

I can't find anything about how long it takes for the eggs on hornworms/stink bugs to hatch. I want to know how long we have to wait for the mystery to be solved!

I have them also! I believe them to be tree frog eggs as adults are all around my porch! These I found in my sweet pea hanging basket! I'm going to carefully place them back in, along the side, so they don't get saturated when I water my plants. ❤️

Yours look like green stink bug eggs to me, but the picture isn't close enough to be rule them in. Put those on red ant hills and maybe the ants can take them on a journey to the center of the Earth. My tomatoes don't like stink bugs of any kind. Not even the lizard sentries running around the garden will eat them. Ant Lions don't eat them, nor can red ants eat them as adults. The sole of my foot is the only solution. Tree frog eggs have transparent sacs.

A quick Google search:

those sacs have spikes Sey...

Serenity, I think they are eggs laid by the shield bug. I don't know much more about it.

I don't mean to hijack this thread; this is just an aside...

I had never heard of stinkbugs until I started reading this forum. Recently I saw a couple bugs I thought might look like the pictures I saw. I just looked up whether we have these bugs in my state and found this article, to my horror!

Apparently we did have a native stinkbug here before, but this one from Asia is like kudzu. I don't know if I've actually seen a stinkbug or not but I don't look forward to smelling them!

Just another reason I love this place to share and learn!

Those things destroyed many of my tomatoes last season, had to spray insecticidal soap on them.

This tiny parasitic wasp from Asia attacks the eggs of stink bugs. (Photo by M. Roche, “Stop the Brown Marmorated Stink Bug” website)

These eggs look very similar, not as green... but these are from a stinkbug,

Max, does the insecticidal soap kill the adults? How about the eggs?

by brown i mean the Brown Marmorated asian variety, we have native stinkbugs here as well.

Place the leaf with the eggs in a screw top jar and keep them warm. You will find out what they are soon enough.

I have not seen them here in WA state. But have seen them in GA and MO, gazillions of them.

One more thing : I am not quite clear on Stink Bug and Assassin bug.In GA they were all over my bean but nothing on tomatoes.

Sey

I think they're green stinkbug eggs.

I have them also idk what kind of eggs they are i think they are tomato horn worm eggs because i found some adults but i dont know if they are their eggs or not

The moths that produce hornworms don't lay eggs in big clusters like that. If they did, given the appetite and size of their caterpillars, they'd quickly defoliate any plant they were laid on and starve to death or risk predation by exposure.

Those are stink bug eggs, IMO. There are many different species of stink bugs, and their eggs also change in appearance depending on how old they are. Those look like relatively recently laid brown marmorated stink bug eggs. http://bugguide.net/node/view/434596/bgpage

When I find them, I usually just snip off the leaflet and crush it well underfoot or I drop it into a container of soapy water I keep around for picking off pests.
