There are all stages of the critters to be seen on the plant and all stages are neat to observe. We've also had some hornworms on the tomatoes and swallowtail caterpillars on the dill, so our diversity is beginning to reap some benefits. Look for them, don't disturb them, but watch. Antlions are part of the order Neuroptera from the family of insects Myrmeleontidae. The name antlion is really applies to the larvae, voracious predators that eat ants and any other insects which fall into their pit.
Some species hide under bits of debris or wood and attack passing insects.
In sandy regions, some species dig a shallow cone-shaped pit and wait at the bottom for an ant or other insect to slip on the loose sand and fall in, to be devoured. Adult antlions resemble dragonflies or damselflies. They are feeble flyers. Antlions have long, prominent, clubbed antennae. The adult is seldom seen in the wild because it is active only in the evening.
