you have to realize, when an insect crawls into the hood of the darlingtonia, it has the hood to crawl around inside before hitting the pitcher itself, If an insect like small grasshopper or caterpiller were to crawl inside, it could crawl to the top of the hood, rather than to the back of the pitcher, chew its way out, and so forth and so on, ive observed this twice with my darlingtonia with small earwigs.
