Silverfish are sometimes mistaken for centipedes, which do inflict painful bites. One way to tell the difference is to note how many legs the bug has. Upon close inspection of a silverfish, youâll see that it only has six legs. o Silverfish are small insects (between 1/4 inch and 1/2 inch) and have shimmering, silver-colored scales.
Look at the picture of the chigger and you will notice it has 6 legs. We are taught early in school that only insects have 6 legs, but here is an exception. After the chigger molts into a nymph it will then have the normal set of 8 legs we associate with arachnids (mites, ticks and spiders).
