One thought on “Black and white butterflies – Photograph by Laura Lecce”
Looking at this photograph I started to wonder – What is the difference between a butterfly and a moth? Simple, right? Not so much. For every rule, there are always exceptions and this is no different. However, here are some of the (exceptions aside) differences between moths and butterflies.
Butterflies are generally a day creature (diurnal) while moths prefer the night (nocturnal). Due to this distinction, moths are usually colored grey, black and brown, while butterflies generally show off brilliantly colored wings. Butterflies have slender bodies and long, thin antennae with a club-shaped end, while moths are stout and furry and have feather-like antennae. Butterflies rest with their wings up (like the butterfly in this image), whereas moths rest with wings down. During metamorphosis, moths make a silk cocoon, whereas butterflies make a smooth and hard chrysalis.
Although these are the general rules, this particular butterfly is not so brightly colored, and for the most part sat with wings down against this tree (see image below). I think these traits ensure successful camouflage with the bark of this tree, and therefore a greater likelihood this butterfly evades predation. This reminded me of the classic evolutionary tale of the peppered moths.
