Examples are formic acid, sprayed by ants in the subfamily Formicinae, carabid beetles, and notodontid caterpillars and quinones released by tenebrionid and carabid beetles. The fauna includes six families of mayflies, five families of odonates (dragonflies and damselflies), twelve families of aquatic bugs, nine families of aquatic beetles, and five families of aquatic flies, but only three families of caddisflies. Water scorpion, any of the approximately 150 species of aquatic invertebrates of the family Nepidae (order Hemiptera).The water scorpion resembles a land scorpion in certain ways: it has scythelike front legs adapted for seizing prey and a long, thin, whiplike structure at its posterior end. An eyeless Nepa is the top predator in a closed Romanian cave system. Surprise combined with rapid escape flight is often a sufficient defense.

These same families provide most of the large number of endemic species (60 to 70). . Nonnative species from four families have been introduced primarily for aquaculture: Cyprinidae (common carp and grass carp), Salmonidae (rainbow trout), Centrarchidae (largemouth bass), and Cichlidae (blue tilapia, redbelly tilapia, Nile tilapia, Mozambique tilapia, and jaguar guapote) (Rodiles-Hernández 2004).

The Monarch butterfly, and many other caterpillars, feed on toxic plants, then sequester those poisons for their own defense. 2005), but a recent compilation for the entire state of Chiapas documents the presence of 111 species. Predators confronted by a cloud of attackers cannot devote attention to defending against each attacker, and reduced predator vigilance enhances attacker chances of scoring an effective sting or bite. Nevertheless, not all insects can, or do, attempt to escape when approached by predators. 87, 88, 93, and 95) ..................................................................................................................................................................................suborder Nepomorpha 2, Antennae longer than head, inserted in front of eyes and visible from above (Figs.

Eventually, when all the nitrogen leaves, the bubble disappears and the insect must return to the surface. ), and noctuid and saturniid caterpillars, providing up to 12% of the crude protein derived from animal foods in men’s diets and 26% in women’s diets during one season of the year (Dufour, 1987).
