![]() All roaches have compound eyes, long antennae, six spiny long legs, and flat, oval bodies covered with a hard shell (or exoskeleton). Adult roaches can grow between 1/2 inch and 2 inches (12.7 and 50.8 mm) long. Young roaches (or nymphs) look the same as the adults, except that they are smaller and have no wings. Male adults have two pairs of wings, but only a few of them can fly. Their forewings called elytra serve as a protective covering for hindwings. Most females are wingless or have very small wings and cannot fly. Roaches can easily be identified through their full-body wings. In short, there is no visible gap between their head, thorax, and abdomen. Their abdomen has 10 noticeable segments, while their head is covered with a big shield structure called pronotum. When viewed from above, their heads are somehow hidden. Related: What Is a Cockroach? | Information and Facts Beetle Identificationīeetles also come in different sizes, depending on the species. They can be black, blue, brown, gold, green, orange, or red, and usually have bright colors. Some beetle species have stripes or marks or a combination of colors. Beetles have short antennae and chewing mouthparts, but some have huge piercer jaws.īeetles have cylindrical, segmented bodies, wherein you can easily notice the separation between their head and thorax. They also have a hard head and two pairs of wings. Although most beetle species can fly well, some are flightless because their veinless and hard forewings meet and are fused to their bodies.Īll beetle species have compound eyes in front of their head and six short legs that have no hard spikes. Each foot has a pair of short but sharp claws and seems to be bending towards its body. Immature beetles are called larvae, which are worm-like grubs with true legs. What Is the Difference Between a Cockroach and a Roach?Īt first glance, some beetle species can be mistaken for roaches. But if you place them beside each other and will close closer, they don’t have the same physical appearance. Their life cycle, eating habits, behavior, and habitat are also not the same. Here are the major differences between a cockroach and a beetle. Life CycleĬockroaches undergo incomplete metamorphosis, which means they pass through three life stages – egg, nymphal, and adult. ![]() Female roaches lay a dark-colored, bean-sized egg case called ootheca. Each egg capsule can contain 15-50 individual eggs. These eggs hatch into nymphs usually from 20 to 60 days. Meanwhile, beetles undergo complete metamorphosis, which means they pass through four life stages – egg, larval, pupal, and adult. Female beetles lay eggs, which hatch into larvae within 7-10 days.
