Names like lightning bug and ladybug are firmly rooted in our language, and despite their scientific incorrectness, are probably here to stay. Fear not, however, for there is a way to distinguish between true bugs and other “bugs” when communicating with other insect enthusiasts. If the word “bug” is directly attached to the end of an insect name (for example, ladybug), then it is NOT a true bug. When referring to true bugs the word “bug” stands alone (for example, giant water bug). Now isn’t that simple ? In parting we can say that all bugs are insects, but not all
insects are bugs!

Bed bugs

There are several species of bed bugs, all of which are parasites of warm-blooded animals. The common bed bug, whose preferred host is humans, is rarely encountered, presumably because of improvements in sanitation. Related species, such as the bat bug and bird bug, prefer to feed on bats, birds, and other wild hosts, but will also feed on humans if the opportunity arises or the preferred host dies or leaves the roost. Adult bed bugs are about 1/4-inch long and reddish-brown, with oval, flattened bodies. Bed bugs prefer to hide in cracks and crevices during the daytime and come out to feed on the host’s blood at night, usually while the host is sleeping.


There are nearly 5,000 different kinds of ladybugs worldwide and 400  which live in North America. A female ladybug will lay more than 1000 eggs in her lifetime. Ladybugs make a chemical that smells and tastes terrible so that birds and other predators won’t eat them. During hibernation, ladybugs feed on their stored fat. The male ladybug is usually smaller than the female.
