Is it a bird, is it a butterfly, is it a drone? What on earth is this exotic creature visiting your garden on a hot summer’s day? It buzzes like a bee, zigzags rapidly from plant to plant, helicopters away and then zooms back again, hovers over flowers like a humming-bird … Ah, there’s the clue – it’s a humming-bird hawkmoth. This super-moth defies all our preconceptions about moths. It is active by day. It can fly fast, with a top speed of 12mph. It migrates here from Europe, just as our summering birds do. It has a proboscis (tongue) an inch long, which it inserts deep into flowers to sample their nectar. And to do this with the necessary surgical accuracy it has to hover, immobile, in front of each bloom by beating its wings at an unimaginable 80 times a second. You then also see its showy colours, with the orange flash on the whirring hindwings transformed into a glowing blur. No wonder the novelist Virginia Woolf described this summer sprite as a creature of ‘tremulous ecstasy’.
The whole hawkmoth family is very striking. Their caterpillars were thought to resemble the ancient Egyptian sphinx, hence their scientific name Sphingidae. Among these, the hummer, as it affectionately known amongst naturalists, is one of the few moths familiar and recognisable enough to have garnered traditional folk names. Their old country nickname in English was ‘merrylee-dance-a-pole’, while the French called it variously fleuze-bouquet (flower-sniffer’), saint-esprit (‘holy spirit’) and bonne nouvelle (‘good news’). Hummers have in fact long been thought a good luck omen and there is a story one would like to believe that on D-Day, 6 June 1944, a small party of them was seen flying over the Channel from France heading for England. In recent years they have been getting commoner and it is believed that a few of them now overwinter here, to emerge from hibernation in the spring. A very welcome addition to our native wildlife, if so.
The favourite food plant of their caterpillars is lady’s bedstraw, while the adult moths are especially drawn to flowers like lavender, verbena and above all red valerian – all common here. When they find a flower-bed they particularly like they exhibit another remarkable ability known as ‘trap-lining’, after the practice of trappers visiting their line of traps at regular intervals and in a fixed sequence. The hummers return to exactly the same patch of flowers at the same time each day, demonstrating an excellent visual memory for particular colours, routes and locations. Check it out yourself. You may have heard of song-lines and ley-lines – let’s plot our local hum-lines.

I have in my hands a wonderful book. It was a treasured possession of long-time Shingle Street resident, Tricia Hazell, whose life and memory we recently celebrated. The book is rather battered and weather-beaten (like the rest of us), but has been honoured by years of constant and loving use. Over twenty years use, in fact, as I can deduce from the spidery annotations in Tricia’s hand over lots of the pages. It’s her moth book, a field guide with her dated records of the many moth species that visited her secluded garden at the southernmost end of Shingle Street.
Tricia would often invite over local moth expert Nick Mason and myself to set up an overnight moth-trap and then early next morning inspect the host of bejewelled beauties that had taken refuge there, before releasing them safely into her garden again. Sometimes we’d invite over a larger group of residents to share the experience and the event would take on the character of a moth-séance, with an attentive circle of devotees gasping reverentially at each new winged spirit summoned up and announced by Nick as our moth-medium. Thinking of them as spirits isn’t a bad analogy, in fact. In the ancient world moths were thought of as ‘souls’, which were released from one’s body at the moment of death to flutter away and disappear into thin air. They continue to be magical creatures of the night, whose presence amongst us feels like an epiphany.
One thing that impressed me about Tricia was that she wasn’t, like some naturalists, just interested in identifying the moths and keeping a tally of them. She asked other sorts of questions, too. Whenever we extracted a new specimen from the box she would carefully note the date we’d seen it, but then insist that we pause so that she could discover in her field guide what specific habitats it was found in, what food plants it preferred, and what time of year it would typically emerge. For example, we’d learn that the gorgeous Small Elephant Hawkmoth we’d just caught could be expected ‘between May and July’, was ‘largely coastal’, had a particular liking for ‘heathlands and shingle beaches’, and was attracted to ‘viper’s bugloss, valerian and honeysuckle’. ‘Well, that all fits perfectly’, she’d conclude cheerfully. Although she’d be amazed to hear me say it, Tricia was an ecologist. The word ecology literally means the study of wildlife in its ‘home surroundings’ – that is, in its relationships with the whole web of life on which it depends. And the mark of a good ecologist is not how much you know but in asking the right questions.
