People usually think of insects (arthropods) as tiny, barely-visible creatures, often completely overlooked in their daily lives. For the most part they are correctly, but there is the occasional impressive giant as well!
It is precisely the world's rain forest and cloud forests that harbor the gigantic insects which resemble the "stars" of any number of D-grade science fiction movies. The giant insects, spiders, and others you have seen on the silver screen are closer to reality than many of us would care to consider! At the same time they are, of course, the very delight of the entomologist and collector.
