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.
Butterfly Legs. Butterflies have six jointed legs and each leg has six parts; coxa, trochanter, femur, tibia, tarsus, and pretarsus. The tarsal segments at the ends of the legs have chemoreceptors which are important for the butterfly to smell and taste.
