They eat voracious leaf eaters and grow rapidly, During growth the caterpillar will shed its skin four to five times before pupating into its adult form.

Many species of tachinids have been introduced into North America from...

PHOTO CAPTION: Goliath Beetle Beetles are one of the main groups of insects. Their order, Coleoptera (meaning "sheathed wing"), has more species than any other order in the entire animal kingdom. Forty percent of all described insect species are beetles (about 350,000 species), and new species are regularly discovered. Estimates put the total number of species at between 5 and 8 million. When J. B. S. Haldane, a British geneticist, was asked what his studies of nature revealed about...
