Differences between butterflies and moths Morphological differences Structure of the body
 Moths tend to have stout and hairy or furry-looking bodies. Butterflies on the other hand have slender and smoother abdomens. Moths have larger scales on their wings. These make them look more dense and fluffy. Butterflies on the other hand have fine scales. This difference is possibly due to the need for moths to conserve heat during the cooler nights whereas butterflies are able to absorb solar radiation.
