Tachinid Fly
A bristly, house-fly-like insect that looks unremarkable at a glance but hides one of the most important ecological roles among flies: its larvae develop as internal parasites of caterpillars, beetles, and other insects, quietly regulating populations across the landscape. Gardeners often welcome tachinid flies as natural allies against crop-damaging pests.

Human Bot Fly
A stout, dark-bodied fly from the American tropics famous for an unusual reproductive trick: it captures a blood-feeding mosquito mid-flight and glues its own eggs to the mosquito's body before releasing it to carry them to a future host. The adult itself is rarely seen, spending most of its short life in shaded forest understory.
