Does anyone have an idea of what these little grub, larvae things are and did they cause this daylily's demise or are they feasting on tissue that died for another reason? There are three grubs/larvae in the picture.

The invoice is dated 04/05/2017 and I planted them after soaking them for a few hours. The other daylilies in the order are doing well- I found a scape on one a couple of days ago...

It's not possible to tell from the picture. If you could extricate the larvae (I know, yuck!) from the plant and place them on a piece of plain paper for a close-up it would enable a better chance of figuring out what they are. Without knowing what they are it's impossible to say if they are secondary to previous damage or the initial cause.

The only known daylily pest that looks at all like what is visible in the picture is the seedcorn maggot:

I have seen beetle larvae in rotting plant tissue that were secondary to another problem based on identifying them. If your larvae have legs (i.e. three pairs at the front) they would not be seedcorn maggots.

I have also seen maggots in decaying daylily tissue that were not seedcorn maggots and were likely secondary. So it's really difficult to know the answer without knowing what they are.

If you still have them you could take them and the plant to your nearest extension office for a diagnosis. If they can't tell what the larvae are by examining them, though, you would be looking at a lab diagnosis which would likely Involve a fee.

Many years ago when I first got into daylilies, larvae were blamed on crown rot. I don't know if that is still true today or not.

Root and crown rot can be caused by all sorts of things, different fungi (e.g. Rhizoctonia, Phytophthora, Pythium, Fusarium, Sclerotium, Armillaria) or bacteria (e.g. Erwinia which has a new name now that I can't remember off the top of my head). Pests can start it off or be attracted to it, I remember one person's lab diagnosis was wireworm damage letting in disease organisms. Any daylily that dies will rot. I remember years ago there was a big fuss on the AHS Robin when someone suggested bulb mites could be involved in daylily rot (which is indeed a possibility), which might be what you're thinking of Cindy? Also nematodes are suspect, as is too much TLC and the list goes on.

From what I can see my guess for Diana's critter is a maggot, but they can be primary or secondary and are difficult to identify. I once found the larvae of lesser bulb flies in my daylilies but to get a positive idea I had to raise them until they turned into flies so that they could be identified. Most people aren't going to want to do that Hilarious!

Could be Sue, I don't remember but one treatment was suggested that was odd, putting Comet cleanser, that has bleach in it, into the hole before you planted the daylily.

Did you contact the person or place you received them from?

Thank you all for your replies! I tip my hat to you.

I have the daylily in a bag in the fridge so I can maybe get out a creepy crawly- I'm okay with bugs : ) (I had to bait my own hook growing up and worm guts are as gross as any bug...) I'll try to do it tonight and post another photo.

I have contacted the nursery, but haven't yet had a chance to check for a reply- busy day (I didn't even get on here til now!).

I guess I'd rather it be a secondary action than the cause of demise. If some little critter has decided to start eating daylilies, that's an entirely different ballgame. I can't imagine those spreading- that's a potential horror story I don't want to read!

***update***

I did receive an email from the company and they are going to credit my account for the purchase price. They mentioned that they had a problem with that cv...

Sighing! gotta find somewhere else order it from...

Ginny, in defense of the company, I think I ordered 6 daylilies and the others are beautiful. One has put a scape... The others were just double fan orders, but I got at least 3 or 4 fans of most of the cv's. They were prompt in replying to my email and refunded my money. They also mentioned they were having trouble with that cultivar. If you'd really like to know, I can share via treemail...

I'm gonna risk that it's not bad genetics on the plant's part and order another one from a different nursery.

I have to pull a "Ginny" and find some more cv's to justify the shipping on the one! Big Grin
