What are these black insects on my Rudbeckia (photos)

Does anyone know what these black insects are on my Rudbeckia?

I spray the  plants and that's keeps the white aphids at  bay. These insects in the photo seem to just keep coming. It is the same every year.

If anyone knows what they are, what is  an effective way to eradicate. I even tried loads  of soap suds last  year, which helped, but very time-consuming applying by hand from a bucket. I find that  a sprayer is not good at applying suds.

    There is no photo to see, but I suspect they're harmless pollen beetles, they fly in from the oilseed rape fields..

    Please don't harm them, there really is no need.. They're early this year but will disappear in a few weeks...

    Has anyone else had problems uploading photos to this site today. Is anyone aware of a technical issue?

  • I've uploaded photos today with no problem, maybe your photos are too big and you will need to make them smaller before you can upload.

    I have found uploading photos to be extremely hit and miss on this site.

    I have never encountered a problem before. Has the method changed?

    I click on the camera symbol, and then select the photo on my device. Previously I would see the option on this site to upload the image, but I don't see this now. Any ideas why?

    it worked OK for me but this is a very small image


  • Check the image size. I had the same problem with a hi resolution (5000 x 3000 pixel) image earlier and when I resized it then it uploaded ok.

    They sound like pollen beetles to me too and they do no damage.

    I don't see no pollen beetles on your photo.image

    You are invited to a virtual visit of my garden (in English or in French).
  • Are these them? Close as I could get I'm afraid.
