A garden changes character after dark. Flowers lose some of their colour and gain scent; hedges become black shapes; a pale moth suddenly appears at the honeysuckle and vanishes again when the torch moves.
Britain has more than 2,500 moth species, and Butterfly Conservation says an ordinary urban garden can support over a hundred. You do not need a moon garden or a collection of white flowers. You need plants for caterpillars, nectar for the adults that feed, shelter and enough darkness for the night to remain night.
Caterpillars are the fussy part
Adult moths are the stage we notice, but most of the eating happens earlier. Some caterpillars will use a wide range of plants; others are loyal to one species or a small group.
Butterfly Conservation recommends plant diversity and points out that native trees such as willow, birch and oak support many caterpillars. Mixed native hedging is good too: hawthorn, blackthorn, hazel, spindle and privet all feed different species.
A hedge therefore becomes more than a boundary. It is leaves, blossom, bark, shelter and a long buffet of caterpillar food packed into a narrow strip.
Give the adults flowers into autumn
Many adult moths feed at flowers. Honeysuckle, evening primrose, sweet rocket and night-scented stock are among the plants Butterfly Conservation recommends, but flowering time matters as much as the romance of a night-scented name.
Ivy is particularly valuable because it can flower into October and November, when much of the garden has already gone quiet.
Pale flowers can be easier to see at dusk, but scent, nectar and a long flowering season matter more than turning the whole border white.
Leave somewhere untidy for winter
Different moths spend winter as eggs, caterpillars, pupae or adults. Old stems, fallen leaves, plant debris, longer grass and sheltered corners can all give them somewhere to wait it out.
Butterfly Conservation recommends leaving some old growth until spring. Conveniently, seed heads and dry stems also give a Cottage Goth garden much of its winter character.
A brown stem in January is not necessarily something you forgot to cut down.
Let darkness be dark
Outdoor lighting looks harmless to us, but excessive artificial light can disrupt moth movement, feeding, mating and development, and may make them easier prey.
If a light is not needed, turn it off. Paths and doors can still be lit when people are using them without leaving trees and borders illuminated all night.
For actually looking at moths, an occasional trap or torch walk is much more interesting than permanent floodlighting.
Go out and see what is already there
Take a torch out after dusk and look slowly around honeysuckle, ivy, buddleia, marjoram, mint and other nectar plants. A warm still evening is a good start.
A moth trap makes the search more systematic: light draws moths into a container where they settle until morning, when they can be identified and released. Butterfly Conservation has guidance on equipment and handling.
The National Moth Recording Scheme accepts records from across the UK, Isle of Man and Channel Islands, so the moth on your shed wall can become part of a much larger picture.
More habitat beats rarer plants
A small garden can still do plenty. More plant cover, a mixed hedge, a patch of longer grass, autumn stems left standing, fewer pesticides and less hard paving all create more places to feed, hide and pupate.
Moths are only part of what arrives. Beetles, spiders, birds and other insects benefit from the same increase in cover and food.
The nicest result is a garden that feels a little less empty when everyone else has gone inside.
