Wikipedia says…

The moths are a paraphyletic group of related to the 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 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 are carried out by adults, normally near or on host for the larvae. The larvae are commonly called caterpillars, and are completely different from their adult moth or 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 develops into a , 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?

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

Nothing - Butterflies are Moths!

What is the difference between: Ladybirds and Beetles Hoverfies and True Flies Orchids and Flowering plants Waxcaps and Fungi What is the Difference… Macro vs Micro A large micro – wingspan c35mm

Mother of Pearl (D. Slade) A small macro – wingspan c15mm

Marsh Oblique-barred (D. Slade) What is the Difference… Macro vs Micro

A pseudo-taxonomic split!

‘more evolved’ than butterflies = Macro ‘less evolved’ than butterflies = Micro

Families that are mostly large species = Macro Families that are mostly small species = Micro

How to identify a moth

No Is it one Yes you know?

Do you think No Yes you know the Check the group/family? species account in the books

Look though No Does the book Yes the related confirm what species you thought? You have your ID

Did you find Yes a species that fits?

Look through No the whole book! How to identify a moth – Is it one you know? Checking the books – what are we looking for?

• Are there similar species? • Is the flight period right? • Is the right? • Is the foodplant nearby? • Is it found in my area?
