I saw a yellow squash plant had saw dust on it near its base. Knowing this was most likely a SVB, I cut it open, and found a tiny one. Since I had already most likely killed the plant, I looked for more and found this large one. I brought some of the stem indoors for later photos. When I came back, I saw there were two more larvae that had apparently come out of the stem, which shows that this plant was severely infested with them.
