and asked what it is but nobody could tell her yet, but it seems to be some kind of parasite or some caterpillar eggs. As you can see, they differ in size since they appear in larger groups, but each egg (I call it so since I have no better name) has a diameter of about 1 cm. On the outside, there are red spikes. Loaction is Germany.
Would be great if someone could tell me what this is and whether it should be removed from the roses.
Thanks in advance
