Eastern Tent Caterpillar Egg Masses

We were in the midst of a mock evaluation at Mono Cliffs provincial park, making our way slowly through an old orchard which had been left to rewild, when Tamara called our evaluator Alexis over to ask if she could suggest a question for the evaluation. Only thing I heard from their quick conversation was “this will be a hard one”. They directed our attention to the end of an Apple branch where a small jeweled formation wrapped around a thin twig, like a bangle or elaborate armband. This broad ring or twig-band, about 3 cm long, seemed to be made up of smaller gemlike circles of gold lacquered together. These smaller circles were about .6 mm in diameter and tightly packed together. There could’ve been 200 of the small gold circles wrapped in this small shiny bundle. I made a guess right away that it must be an egg mass, but I didn’t know who made it. It was mysterious to me. I wrote out my answer and shared it with Tamara and waited for the big reveal.
