I lifted a nodding cane of raspberry to check for fruit, and found as well a crab spider crouched there, its light-green, almost translucent coloring a perfect complement to the red of the berries. The spider drew back into the berry, and I let the cane nod back down.
Last year, to the week, I didn’t see the spider until I had the fruit inside. I took her photograph and released her back into the berry patch.

Do crab spiders eat raspberries?
