imagine a population of beetles: 1. There is variation in traits. For example‚ some beetles are green and some are brown. 2. There is differential reproduction. Since the environment can’t support unlimited population growth‚ not all individuals get to reproduce to their full potential. In this example‚ green beetles tend to get eaten by birds and survive to reproduce less often than brown beetles do. 3. There is heredity. The surviving brown beetles have brown baby beetles because this trait has

that feed directly on the corpse. They usually depend on decaying remains as a food source‚ so they are very aggressive in their search for food. This is why they arrive at the dead remains only minutes after death. They include both flies and beetles. Flies are usually the first to arrive to the deceased body. The most common one is the blowfly‚ which is metallic green or blue. Their life cycle is what helps to determine how long a body has been decaying. Their life cycle is developed in six

Cutter Bees; looks are very distinct. They are not like Honey Bees; they do not look like wasps or hornets. They almost resemble more of a beetle in a way. A beetle has a hard shell on their back and most beetles we think of are black. Same as for Leaf Cutter bees‚ have a hard black shell that surrounds their entire body like a bullet proof vest. Just like a beetle‚ a Leaf Cutter Bee they can turn their head a complete one hundred and eighty degree for defence against predators. Unlike a Wasp‚ Honey

The global temperature increase has changed the length of the seasons on Earth‚ which has in turn affected the lives of insects such as beetles that feed on trees (which has added to the decrease in abundance of the Earth’s forest) and mosquitos that carry infectious diseases that are now able to spread at an increased rate (page
