True Bugs are one of the most diversely represented groups in the FBM, of which there are 60,000 living species in this order. Their impressive diversity is theorized to be related to the diversification of flowering plants beginning in the Cretaceous period.
Living stinkbugs emit a rancid unpleasant scent when disturbed as defense. Some species feed on other insects, most feed on plants. There are about 5,000 living species today.
