Yes. All insects, like all arthropods, have bilateral symmetry. Other arthropods include arachnids, crustaceans, centipedes and millipedes. Bilateral symmetry means something has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.

Characteristics of a echinoderm?
Deuterostome embryo developmentSecondary radial symmetry: larvae have bilateral symmetry (radial symmetry thought to have evolved from sessile forms)Five radial parts; sea urchins and cucumbers by folding "arms" upwards and fusing their edges; sea cucumbers lay on "side" and developed pseudo-bilateral symmetry, i.e. have distinct upper and lower sideEndoskeleton: calcite plates = ossicles, covered by epidermis, may be single plates (flexible body) or fused (solid shell, sea urchin)Spines on calcite plates give "spiny skin" (phylum name!) sea urchin spines are endoskeleton and covered by thin skin!
What is another name for center of symmetry?
line of symmetry
Are annelids bilateral?
No, they are protostomes. Protostomes form their mouth first in their embryonic development (it also means ´mouth first´). Deuterostomes form their anus first, and their name means ´mouth second´. Deuterostomes include echinoderms such as starfish and sea urchins, and us chordates including the vertebrates. Everything else, save for sponges and jellyfish, is a protostome.
