I took a few minutes to walk around my small orchard yesterday evening and saw these pests on one of the pear trees.
First, does anyone know what they are? All the online pictures of pear pests show them fully grown (or at least all I could find in a 10-minute search).
Second, can I assume they're pests, and not good? (There I am with this whole white hat-black hat thing again! In my newbie world, things need to be good or bad. Shades of grey will come later, with wisdom.)
Third - what to do about them? Spray them off with water or soapy water?
