What Counts as a "Bug" in This Directory?

Scientists use the word "bug" in a narrow way. True bugs belong to the order Hemiptera. But most people use "bug" much more loosely. They mean any small crawling or flying creature, including beetles, cicadas, and even damselflies. This directory follows that everyday meaning, so you will find true bugs alongside beetles and other insects that people commonly call bugs.

Knowing the difference matters if you are trying to identify something specific. A ladybug, for example, is actually a beetle, not a true bug. We explain details like this on each individual bug page.

Beetles

  • Stag Beetle — known for the large, antler-like jaws on the males
  • Beetle Bug — a general look at common backyard beetles
  • Ladybug — the familiar red beetle that helps control garden pests
  • Yellow-Spotted Ladybug — a lesser-known ladybug relative with a different pattern

True Bugs

Flying and Aquatic Insects

  • Emanated Cicada — famous for its loud summer song
  • Damselfly — a slender relative of the dragonfly, often found near water
  • Firefly — the beetle that lights up summer nights with its own natural glow

Why Learning About Bugs Matters

Bugs are not just background noise in nature. They pollinate flowers, break down dead plants, and feed birds, frogs, and countless other animals. Take ladybugs and fireflies away from a garden, and the whole food chain feels it. Even bugs people consider pests, like boxelder bugs, play a role in their ecosystem.

Our farm background taught us this firsthand. Bugs decide whether a crop thrives or fails. A field full of ladybugs usually means fewer aphids and healthier plants. That kind of hands-on experience shapes how we write about bugs here — grounded in what actually happens outdoors, not just textbook facts.

Frequently Asked Questions

What is the difference between a bug and an insect?
All bugs are insects, but not all insects are bugs. In strict scientific terms, "true bugs" belong to the order Hemiptera and have piercing mouthparts for sucking plant juices or fluids. In everyday language, though, people call almost any small crawling insect a "bug," including beetles and cicadas.
Are the bugs in this directory dangerous to humans?
Most of the bugs listed here, like ladybugs, fireflies, and damselflies, are completely harmless to people. A few, such as the eastern leaf-footed bug, can be a nuisance to garden crops but pose no direct threat to humans. None of the bugs in this directory are venomous or aggressive toward people.
Which bugs are good for my garden?
Ladybugs and yellow-spotted ladybugs help by eating aphids and other soft-bodied pests. Damselflies help control mosquito populations near ponds and streams. Fireflies and stag beetles cause no harm and simply add to a healthy backyard ecosystem.
Why do boxelder bugs gather in large groups?
Eastern boxelder bugs cluster together on warm, sunny surfaces like walls and fences, especially in fall. They do this to soak up heat before winter and to stay close to boxelder or maple trees, their main food source.
How can I identify a bug I found in my backyard?
Start by noting its color, size, number of legs, and whether it has wings. Compare what you see with the bug profiles in this directory. Each page includes clear photos and identifying features to help you match your find with the correct species.
Will more bugs be added to this directory?
