Really not close enough to tell for sure but the one with the white spots looks like it could be ladybug larvae. Could be asparagus beetle instar too but can't say for sure either way. Can't tell what the brown beetle is but it does not look like an asparagus beetle. Likely both are there eating the aphids that are on the plant.

Looks like my asparagus beetles do.

the spotted one is an asparagus beetle. they are eating asparagus not aphids.

Yes, those are Asparagus beetles.

Ok hand picking and killing them BUT should I do more? Eggs might be laid already? Willing to spray and not pick for a couple weeks.

the beetles lay eggs on the stalks...little black dots. if you pick the asparagus then you remove the eggs from the asparagus patch so picking them is a good thing. hand picking adults is difficult as they fly and also will drop to the ground when you reach for them. what would you spray with? i have used pyganic but if you aren't growing organically there might be other options.

I wouldn't spray anything until you are done harvesting for the season. I use a container of soapy water and hold it under the beetles and they either fall off into the container on their own or I knock them off into it. The larvae are easy to kill after they hatch by hand squishing but it is a little bloody. They look like tiny little slugs and will usually be on the ferns.

I find that if you cup your hand under the beetle before attempting to pick it off, when it drops it will drop into your hand. The same technique works with lily beetles. Sometimes, if you keep a close eye on the fern you can spot the eggs and strip them off with your fingers. Or just remove the whole section of fern if it's too badly infested.

Found lots of eggs, I can strip them off but is knocking them to the ground going to insure they die? Seems like many might make it especially if they are ready to hatch.

Knocking them off won't kill them but it might make the larvae work a little harder to get back on the ferns. Just take some duct tape and use the sticky side to remove the eggs from the spears. I use that method for squash bug eggs/nymphs.

I should have been clearer. Once they drop into your hand you squash them. Striping the eggs with fingers works either because they get crushed as you do it, or, since they are eggs, they can't climb back on the plants and they have no food to survive. If you are dubious just make sure you kill them somehow, anyhow, after they're removed.
