The simplest organochlorine compound is chloromethane, also called methyl chloride (CH 3 Cl).
Although ticks are commonly thought of as insects, they are actually arachnids like scorpions, spiders and mites. All members of this group have four pairs of legs as adults and have no antennae.Adult insects have three pairs of legs and one pair of antennae.here are two groups of ticks, sometimes called the hard ticks and soft ticks. Hard ticks, like the common dog tick, have a hard shield just behind the mouthparts (sometimes incorrectly called the head); unfed hard ticks are shaped like a flat seed.
3. Stick insects not only look like sticks, they act like them, too. Stick insects are so named for their effective camouflage among the woody plants where they feed. They're typically brown, black, or green, with stick-shaped bodies that help them blend in as they perch on twigs and branches.tick insect eggs may attract ants, which then collect and store the eggs in their nests. Stick insect eggs that resemble hard seeds have a special, fatty capsule called a capitulum at one end. Ants enjoy the nutritional boost provided by the capitulum, and carry the stick insect eggs back to their nests for a meal.
