I have lots of bugs on my hemeros! The blooms have gillions deep in the blooms, but the ones I am deheading have them crawling out and flying away. They don't seem to get on any other plants. I put some insecticidal soap on them, but that didn't seem to do much good. I'm attaching a photo of a deaheaded bloom with bugs. The hand should show the relative size. Any guesses as to what these devils are?

They look like sap beetles. I'm not sure the size is right but they resemble this one, as an example:

Is there any way you can get a closer picture to show more detail of one?

Any evidence they are doing damage to the blooms or the plant? Or are they only showing up on those spent blooms that get deadheaded? If there isn't any discernible damage to the plant or blooms, I'd probably just ignore them.

Given their small size and if they're in open blooms, another possibility is pollen beetles, see:

Again, a close-up of one would help.

Hmmm... they do look a lot like sap beetles, but I can't determine if those can fly. These can. Yes, there are a ton of them on the new blooms, and I think some damage results as I deheaded this morning and had more to deadhead when I went out to get a picture of them on a new bloom. There is damage to the new one as well as a few I had to deadhead this afternoon. I'm attaching a picture of a new bloom. I don't think you can see how many are down deep in it, but they are sure in there and you can see damage. A friend with a macro lens came to take a picture with my finger in it so you can see just how small they are, but I can't get anything closer. Thanks for the ideas...what can I do about them if they are sap beetles? They're sure doing something BAD!

Dang! They look a lot like pollen beetles, too! I can't see them close enough to tell!

Check out the pollen beetle link, Barbalee. We probably cross-posted and you missed it. I think they might be nearer the right size. If you can kill one (freezer or rubbing alcohol) and set it on white paper carefully so as not to knock off antennae or legs (can be difficult) you may be able to get a closer more detailed picture for us.

Cross-posted again lol. Try the close-up as described above, if you have a magnifying lens try taking a picture through that.

I'll give that a shot, Sue... I'll try the rubbing alcohol. Thanks!!

Well, I got some dead ones, but I still can't see much specific on 'em. I pulled these from a new bloom dumped in alcohol. I appreciate you, Sue!

It was worth a try! I think I can see them more clearly on the bloom. The pattern looks like the sap beetle but I think it is too big and yours are nearer the size of the pollen beetles. If you have a ruler can you check the length of one? Then I'll see which beetle has a range that comes closest to that measurement. I might not be able to do it until tomorrow though as we have family here for the evening.

Enjoy the family...it's FAR more important! Measuring the things, I get 1-3 mm, so that sure looks like pollen beetles then. Yuck!! Suggestions? How the heck can I get rid of them? Thank you!!! Thank You!

I got the beetle book out and sap beetles can be 1-12 mm depending on species. Pollen beetles can belong to any of several different families including the same family as sap beetles. I can't see enough detail to ID them any closer. I think the ones on the holes in the flower also have the light coloured pattern on their backs? Are they on all the daylilies? Since they are damaging the flowers I would go around with a sprayer of insecticidal soap and zap them as you see them. Do you have any farmers' fields nearby?

If they aren't on all the daylilies you could just carry a hand-spray bottle when you go around your flowers and get them on a daily basis, you just need to get the insecticidal soap directly on the beetles. Hard bodied insects are less susceptible to soap sprays than soft-bodied ones like aphids but it's worth a try

Edited to add try not to get the soap on the leaves if the weather is hot as it could damage them somewhat.

Yes, they have lighter colors on the shell/wing parts than on their head. They're on the vast majority of the daylilies, but they seem to like the lighter colors. I don't know of any farmer's fields close by, but I've heard of infestations on canola fields that aren't too far away. I guess insecticidal soap is the way whether they're sap or pollen beetles...I'll spray until I'm blue! I hope the family visit was good, Sue! Thank You! Thank You!

Thanks, Barbalee, family now gone home to beat the storms - we're under a tornado watch currently. Yes, pollen beetles have been reported to be a problem on ornamentals near canola fields. I could do a better job of IDing your beetles if I could get one under my microscope. I think from the general type of antennae it is one or the other (or one that is both!). If the insecticidal soap seems to just knock them out rather than kill them then we can try and figure out another possible treatment. I think you can maybe get Trounce there which has a pyrethroid added to the insecticidal soap, that could be another option. (Thx for the acorn Smiling )

I sure hope there's no tornado for you and yours!! I think I nailed the beetles... I took all of the blooms very carefully so as not to dislodge the bugs and put them in trash bags in the dumpster. This morning I had just a few, and I think the soap got 'em. I'll be watching hard, but I've sure got few instead of a zillion! Hurray! I sure hope your weather is fine, Sue, for both you and your family! Thank You!

Sounds like you did a good job! One trick that you may have already figured out is to invert an open plastic baggie over a bloom (if you can do it without knocking the other buds off) because insects tend to fly upwards when disturbed so fewer manage to escape. Of course some contrary ones drop down instead of fly up but it might be worth a try.

Tornadoes didn't materialize, fortunately, not here anyway. Thank You!

Yep, that's how I took the blooms... maybe that thought sent the tornado away! nodding

Thank You! Next time we have a tornado watch I'll ask for you to send some more thoughts this way Hilarious!
