Eggs and a Predator

While searching the wild cherry tree for a hibernating caterpillar, I found an egg mass.

Eastern tent caterpillars will hatch from these in the spring … unless the spider I saw when I found them, decides to return. The white area shows where the spider had gotten through the dried foam to the eggs. The egg mass measured 1/2 inch long.

The uncooperative spider didn’t like my being there. Its silhouetted on the right side of the branch, with its abdomen down. The little bump is its cephalothorax (fused head and thorax). Legs go on up together from the body. I don’t know how many of its 8 legs do that.

I’ve seen tent caterpillar egg masses eaten or partially eaten before. I never suspected a spider … not that I’d given it much thought.

  1. The macro lens that you are using is a good one. Photos are clear. I don’t know how you find these itty bitty specimens.

    • I use a Canon PowershotSX130. I was looking for a tiny hibernating caterpillar (in 5 previous blogs) and found the egg mass. These masses are common in wild cherry trees. Sometimes I think the subject finds me.
