| | Iridescence on Butterfly Wings (Site not responding. Last check: 2007-11-05) |
 | | Butterflies differ from moths structurally in that their antennae are clubbed at the end and they lack a frenulum, a spine-like device which connects the front and hind wings of most moths. |
 | | The general understanding of the taxonomic difference between them, is that butterflies have slender bodies, are brightly coloured and fly in the daytime, whereas moths have stout bodies, are dull coloured and usually fly at dusk or at night. |
 | | Some of the Lycenid family of butterflies that are generally found on the South Coast, for example the Adonis Blue and the Long-Tailed Blue are noticeably iridescent on almost all of the top surface of their wings. |
