   🚨 ARTHROPOD OF THE DAY 🚨
   
   Blue morphos are large, brilliant blue butterflies that live in the forests of South and Central America, and also in parts of North America.
   
   The most striking aspect of the butterfly’s appearance is its iridescent blue wings. They seem shiny and metallic. However, they are not actually blue.
   
   The blue is not caused by pigmentation; it is actually caused by the way light reflects off of microscopic scales on the backs of the butterfly’s wings. The structure of the scales is tetrahedral (pyramid-shaped), and they reflect light. The colours vary depending on the angle from which they are viewed.
   
   The caterpillar is reddish-brown with bright spots of lime green on its back, and covered in stinging hairs for protection. These hairs can irritate human skin. The caterpillars spend their days feeding on a variety of plants. If disturbed, the caterpillar will secrete a fluid that smells like spoiled butter.
