Img_4791 Plock of Kyle harvesman

A harvestman with 2 bright orange blobs on its back. There were several others with the same blobs on their backs nearby. Can anyone tell me what the blobs are?

Attachment on Opilione

Hello Jane I am not sure about these but it may be some sort of parasitic eggs ?? They look eliptical (In the same way Tachnid Eggs attach to Shieldbugs )Interesting Observation

Parasitic mites ?

I think they're parasitic mites. If you put the search words 'harvestman' and 'parasite' into Google it picks up a lot of pictures showing in more detail the red 'blobs'.

They may be red spider mites which often hitch a ride on other insects.
