Introduction to Macro-moth Identification David Slade Lepidoptera County Recorder (VC41) Introduction to Macro-moth Identification • What are moths? • How do you identify them • Moth families • Mysteries and pitfalls What is a Moth? Wikipedia says… The moths are a paraphyletic group of insects related to the butterflies and belonging to the order Lepidoptera. Most lepidopterans are moths and there are thought to be approximately 160,000 species of moth, many of which are yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. a group is said to be paraphyletic if it consists of all the descendants of the last common ancestor of the group's members minus a small number of monophyletic groups of descendants, typically just one or two such group Wikipedia also says… Lepidoptera is a large order of insects…. It is one of the most widespread and widely recognizable insect orders in the world. The term was coined by Linnaeus in 1735 and is derived from Ancient Greek λεπίδος (scale) and πτερόν (wing). Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. It is among the four most speciose orders, along with the Hymenoptera, Diptera, and the Coleoptera.[1] Lepidopteran species are characterized by scales covering their bodies and wings, and a proboscis. The scales are modified, flattened "hairs", and give butterflies and moths their extraordinary variety of colours and patterns. Almost all species have some form of membranous wings, except for a few that have reduced wings or are wingless. Like most other insects, butterflies and moths are holometabolous, meaning they undergo complete metamorphosis. Mating and the laying of eggs are carried out by adults, normally near or on host plants for the larvae. The larvae are commonly called caterpillars, and are completely different from their adult moth or butterfly form, having a cylindrical body with a well-developed head, mandible mouth parts, and from 0 to 11 (usually 8) pairs of prolegs. As they grow, these larvae will change in appearance, going through a series of stages called instars. Once fully matured, the larva develops into a pupa, referred to as a chrysalis in the case of butterflies and a cocoon in the case of moths. A few butterflies and many moth species spin a silk case or cocoon prior to pupating, while others do not, instead going underground. What is a Moth? Dave says… Amazing insects with scales on their wings! What is the Difference… Butterfly vs Moth • Flight time • Butterflies fly during the day • Moths fly at night • Antennae • Butterflies have clubbed antennae • Moths have feathered ones • Posture • Butterflies rest hold wings upright • Moths hold them flat • Overall impression • Butterflies are pretty colours • Moths are dull brown A day flying moth with clubbed antennae!
