Mention the word ‘moths’ to people and I suspect the majority are likely to think about those nasty critters whose larvae consume clothes or chew carpets. I confess to being a bit indifferent to moths in general until I saw a humming bird hawk moth in my town garden years back. That remarkable encounter made me sit up and take note yet it wasn’t until I moved back to the country that I eventually got actively involved this spring in entering the world of the amateur lepidopterists.

There are some 50 species of butterflies and 2,600 species of moth in the UK. Roughly 900 of those are macro moths and the rest a bewildering range of micro moths, many virtually indistinguishable one from t’other to the non-expert eye.

Where to start when trapping and identifying specimens? Online research around the options makes for a good start. Thinking through what best suits your situation when matched with what’s affordable and you’re ready to proceed. There are three main types of moth trap, named after the experts who devised them. The Heath trap consists of a collapsible rectangular metal box with a funnel and fluorescent UV bulb. The larger Skinner trap has a slot entrance below the light. The Robinson is a large round, non-collapsible trap, most likely to catch and retain the largest number of moths. It’s also the most expensive to buy. I opted for the Heath model.

I nearly got a version powered by an extension run from the house mains. On reflection thought that a daft idea as the more places to set the trap of an evening around the garden (or beyond) would be a much better proposition. So I also bought a battery and charger. It’s proved a great investment, not only giving me pleasure as well as visiting friends and family, young and old alike.

My first and most numerous species caught, back in April, was ‘Hebrew Character’; so called from the dark marks on its forewings that look like letters in Hebrew script. They’ve now been replaced as most numerous by a scrum of large yellow underwings, clustering in a gang around the egg boxes I’ve furnished the floor of the steel box with.

Although Latin nomenclature is essential in classification worldwide it is surely the common names, reflecting archetypical characteristics, that catch the imagination and lodge in one’s mind. Here are a few favourites:

Burnished brass. Small, widely distributed, lover of damp places, feeds on low lying plants like red valerian, honeysuckle and buddleia…all of which we have in the garden. The wonderful metallic sheen on the forewings is a entrancing sight.

Wainscot. Named for resemblance of wings to the ribbed wood raised panels of interior walls, introduced in Tudor times. The caterpillars of this common moth feed on grasses and our meadow and surrounding pastureland provides ample acreage.

The Herald. Scalloped broad forewings and splashes of orange colouring give this medium size moth a distinct dynamic appearance hinting at speed with a purpose. It overwinters in barns and outbuildings and we have both. The caterpillars feed on willow trees and again no shortage of them hereabouts. Small resident birds like tits and robins we see working wands of willow in the spring are probably feeding on the larvae of the many species of moths and other insects that live there.

Riband wave. I love the poetry of the name reflecting the subtle patterning of its wings displayed when at rest, drawing on the imagery of a sandy seashore.

The Antler. The pale markings on the forewings resemble deer antlers. This medium size moth is at home here in upland moorland country, its caterpillars feeding on acid grasslands. The antler also flies in the daytime, feeding on thistles and ragworts.

Poplar Hawkmoth. Sure to wow any observer when first sighted. Varieties of hawkmoth, like their avian namesakes, spread their wings and the large size and studied stillness never fails to impress. Most of my specimens (or the same ones recaptured) feature when the trap is left near the mature poplar tree in the east end copse.

As spring turned to summer the moth count increased in variety and number. Warm, still, humid nights with good cloud cover tended to produce the greatest number of captives. I discovered that when the trap was set in amongst shrubbery and trees it upped the number and variety even more. Some species flew off immediately on opening the container in the morning but the vast majority remained static, happy to linger, having to be emptied out at the same collecting spot once recorded.
One morning one of the parent swallows nesting in the eaves above the porch where I’d parked the open trap, flew down and snapped up an unfortunate escapee as it fluttered skywards. Daytime insect feeding birds apart, bats are the main nocturnal predators, and these we see regularly so the numbers of insects must be high enough to sustain populations, which is good. Nationally, the situation is not so good. There’s been a worrying decrease in UK macro moth numbers in recent decades, much of that due to human activity, and that has had a knock on effect in the wider ecosystem.

So far I’ve identified around 50 species in this Northumberland garden. Use of the phone camera has proved invaluable as it utilises AI to help identify a subject by family or common name; a real boon to beginners like me. Bernard Skinner (he of the trap) produced ‘Moths of the British Isles’ handbook, a definitive colour identification guide, back in 1984. My updated ex-library copy is still invaluable too, with 1,600 of the UK’s moth specimens recorded, with very useful notes. There are lots of good guidebooks out there so well worth investing in one. Triangulate by visiting excellent online sites too, like Butterfly Conservation charity https://butterfly-conservation.org/ or joining a Facebook moth trapping group.

A fascinating element of moth survival technique is camouflage. Some species I’ve come across when trapping are past masters at the art. The Buff tip for example. At rest its wings are held almost vertically against the body with two buff area in front of the thorax (body) at the tip of the forewings. Looks like a twig or chipping. Colouration varies but its favoured tree is birch, into whose bark it merges. On the wing from May to July, it’s one to marvel at.

A problem gardeners like us who have an orchard is probably more alarming than deadly. The apple ermine moth lays its caterpillars on apple trees. The ghostly tent like web that surrounds the larvae give protection from bird predation but the caterpillars devour the leaves and can denude the tree and restrict budding. I’ve had to carefully peel off and destroy the tent caterpillars found in our trees each spring.

When I came across the handsome white ermine moths in the trap I mistook it for its cousin causing the problem so was relieved to discover the difference when looking it up. Appearances are more obvious when you see them together.

The white ermine’s caterpillars live in webbed tents feeding on nettle, dock and other common vegetation. Apparently this medium size moth has few predators because it is highly poisonous. (But not to humans if touched). Like some other moth species they have another defence mechanism against predators; dropping, seemingly lifeless from their perch, into undergrowth beneath.

I’ll look forward to what the autumn brings to the moth mix. As one observer remarked, ‘trapping is like a lucky dip for adults’. For me it’s yet another strand to an understanding of the wonders that surround us in the world wide web of nature and the farmed environment.
