If someone asks, "Do you have a bug?" are they asking about:
Names matter. People can describe a lot of different things with the slang word "bugs" but this leads to confusion about who and what they really mean.
So many insects are colorful and harmless and beneficial to humans! They are like strange but gentle aliens who visit our world daily, and there is much to learn from them. Let's sort it out and learn how these cool creatures help to hold our world together.
Most of the small life you find creeping, crawling, swimming, jumping or flying is likely to be an invertebrate (animals that have no backbone). But just because they are spineless doesn't mean they are cowards. These creatures are brave and mighty compared to much larger organisms. 97 percent of all animal life on Earth are invertebrates!
There are different Invertebrate groups; crustaceans (like crabs and shrimp), insects (for example dragonflies and beetles), arachnids (like spiders or scorpions), worms and annelids.
"Bug" is only correct for 1 order of insects, the Hemiptera, or true bugs. This order has mouthparts built for piercing and sucking liquid food and includes aphids, cicadas, stinkbugs. Lightning bugs and Ladybugs are not true bugs (Hemiptera). Both are actually beetles, insects that have a hard wing case protecting the hind wings and tummy.
Did You Know?
Computer bugs, slang for something gone wrong in a program, are actually named for a real insect. In 1947, technicians working for computer scientist Grace Hopper found a moth inside her computer. The trapped moth was making the machine malfunction. Once removed, they reported that the computer was “debugged”. They taped it onto her notes with a little joke that is now part of our everyday language.
