    There are only two reasons for an animal to be nocturnal; to escape predators or to venture forth in a cooler time of the day. Evolution is a tough game to play with the death penalty to the losers. To avoid competing with many animals running around in the daytime a lot of animals have turned nocturnal. In desert climates they go nocturnal to avoid the heat of the day.

    The lion is not nocturnal, but they often hunt at night and they lay in the shade resting during the day. What makes an animal nocturnal is if it sleeps during the day; like bats do. Bats have developed an acute sonar to hunt for their prey; mostly insects that like to fly at night and avoid birds who are normally only active during the daytime (diurnal). Owls are also nocturnal and they have well developed eyes and superb night vision so they can hunt at night. Some of their prey, rodents like rabbits and rats hide during the daytime and only come out at night so the owl changed into an animal that can hunt better at night. All cats have specially constructed retinas that concentrate and reflect more light into the pupil. This is why when you shine a light on a cat at night it seems that their eyes are glowing.

    Crickets are one insect that is nocturnal so they can avoid most birds as well as frogs, lizards, salamanders, and spiders. Even if the predator is nocturnal too their vision is compromised. Most lizards and salamanders are cold blooded so they only come out at night.

    Crickets are omnivores, meaning they will eat anything plant or animal, including dead crickets if no other food is available.

    Male crickets chirp to attract females and that chirping rate is tied directly to the temperature.

    According to Wikipedia: http://en.wikipedia.org/wiki/Cricket_%28insect%29#...

    “Crickets, family Gryllidae (also known as "true crickets"), are insects somewhat related to grasshoppers and more closely related to katydids or bush crickets (family Tettigoniidae). They have somewhat flattened bodies and long antennae. There are about 900 species of crickets. They tend to be nocturnal and are often confused with grasshoppers because they have a similar body structure including jumping hind legs….

    Crickets chirp at different rates depending on their species and the temperature of their environment. Most species chirp at higher rates the higher the temperature is (approx. 60 chirps a minute at 13°C in one common species; each species has its own rate). The relationship between temperature and the rate of chirping is known as Dolbear's Law. In fact, according to this law, it is possible to calculate the temperature in Fahrenheit by adding 40 to the number of chirps produced in 15 seconds by the snowy tree cricket common in the United States.”

    Where I live crickets can be a major problem they are attracted to the lights of a store and engage in a mating frenzy and soon after die leaving hundreds of corpses for the store operators to clean up.

    According to Wikipedia: http://en.wikipedia.org/wiki/Mole_cricket

    “Mole crickets are relatively common, but because they are nocturnal and spend nearly all their lives underground in extensive tunnel systems, they are rarely seen.”

    Any crickets that live in a hot desert climate would probably be nocturnal to avoid the heat of the day.

    Crickets are somewhat related to grasshoppers and more closely related to katydids or bush crickets. Many grasshoppers and katydids are diurnal so the cricket doesn’t have to compete with them at night.

    According to Wikipedia: http://en.wikipedia.org/wiki/Nocturnal

    "As an animal behavior, nocturnality describes sleeping during the daytime and being active at night - the opposite of the diurnal human lifestyle, and that of those animals with which we are most familiar. The intermediate crepuscular schedule (twilight activity) is also common. Some species are active both during the day and night. Living at night can be seen as a form of niche differentiation, where a species' niche is partitioned not by resources but by time itself, i.e. temporal division of the ecological niche. It can also be viewed as a form of crypsis, in other words an adaptation to avoid or enhance predation. There are other reasons for nocturnality as well, such as keeping out of the heat of the day. This is especially true in deserts, where many animals' nocturnal behavior prevents them from losing precious water during the hot, dry daytime. This is an adaptation that enhances osmoregulation.

    Many species which are otherwise diurnal exhibit some nocturnal behaviour; for example, many seabirds and sea turtles attend breeding sites or colonies nocturnally to reduce the risk of predation (to themselves or their offspring) but are otherwise diurnal. Some animals are not really nocturnal and are instead crepuscular, being mostly active in twilight.

    Nocturnal animals generally have highly developed senses of hearing and smell, and specially adapted eyesight. In zoos, nocturnal animals are usually kept in special night-illumination enclosures to reverse their normal sleep-wake cycle and to keep them active during the hours when visitors will be attempting to see them.

    Some animals, such as cats, have eyes that can adapt to both night and day levels of illumination. Others, e.g. bushbabies and bats, can only function at night."
