At the gateway between Europe and Africa, there is biodiversity galore! Avian migration is the most visible and celebrated, and we spend a lot of our time looking up. But to never look down would be to miss out on so much, including some of the best moth-trapping opportunities in Europe. That´s why, with the help of acclaimed international moth expert Dave Grundy, we´ll be running a trip in May 2019 to look more closely at the gorgeous local nocturnal Lepidoptera under our very noses!
We caught up with Dave to ask him about all things moth-y, and more!
So Dave, what drew you to the Straits? Why would you recommend it to British moth-ers?
The Straits is just an amazing place! There are so many moths and a higher diversity all year round, and it’s all in brilliant scenery with great hospitality from local Andalusian people!
I first started coming here simply to extend the mothing season. I was fed up of opening traps in the cold to find none, or maybe one moth huddled in the corner of the trap, so I headed south, to look forward to opening a trap and finding 60 species in it!
I got hooked, really – it is a real biodiversity hotspot at the crossroads of two continents, the far south of Spain in Europe and the far north of Morocco in Africa. The geology is diverse due to the collision of two continents in geological time and this leads to a diversity of fauna and flora and of course this includes a very rich fauna of moths.
The mothing sites are great and from a totally different biogeographic area – trapping Mediterranean olive scrub and cork oak forest in an area where new moth species are likely to be discovered! What’s not to get excited about?
We know you´re often to be found trapping at Europe´s most southerly point at Fundacion Migrés coastal HQ. And also enjoying a pizza at top veggie restaurant Tarifa Ecocenter! Any other favourite hangouts in the area?
I love to stay at Huerta Grande up in the hills above Tarifa. From there you can step into both the coastal Natural Park of the Straits with its olive scrub and coastal habitats and inland to Los Alcornocales Natural Park, which is on inland hills cloaked in humid cork oak woodland.
There´s birds to enjoy too, for those that like that sort of thing! The Straits is probably most famous for its twice-yearly raptor migration event during which 250,000 soaring birds pour across the sea. Plus there´s loads of nice resident birds in local coastal, wetland and woodland habitats. You get things like Crested Tit and Short-toed Treecreeper just hanging around the log cabins at Huerta Grande!
We remember coming to inspect a trap with you and you showed us our first Giant Peacock Moth. Europe´s biggest moth! It was mega! What are some of the other cool species you’ve trapped in Andalusía?
There´s so many! Goldwing, Passenger, Alchymist, Latin, Pale Shoulder, Striped Hawk, Lydd Beauty, Four-spotted, Eutelia adulatrix, Porter’s Rustic and Speckled Footman to name just a few.
I don´t really have a favourite but I do like Lemonia philopalus, a lot! Why? – is more difficult to say – big and furry and stripy with amazing wing and antennae patterns. And also crazily it needs heavy rain to come out – and this is because it pupates in the soil and needs the soil softened by rain to emerge!
For the newcomer, how does mothing with a local expert help?
Mothing in Spain is difficult, if not impossible for non-local people who don´t at least have mothing friends here. You need a moth-trapping licence, which is expensive and really difficult to fill in – in Spanish, of course!
Best to hook up with somebody who has all the kit and permissions, so you don´t have to worry about it. I have the all the paperwork and licences you need for trapping. I have the permissions off local landowners to trap in the area. I bring lots of traps here from Britain in my van – so when people come mothing with me they have access to five or more moth traps every night to see what is inside – and no need to bring your own trap! If you fly out here, you would be lucky to squeeze one trap into your suitcase.
Over the ten years I´ve been coming here I´ve been lucky enough to make some great friends in the local mothing community – a group I´m working hard to build! I´ve got lots of gen now on where the good sites are for moths. It´s been fascinating building up experience trapping in olive groves, or cork oak forests or sand dunes by the sea. There are so many special moths to see! I feel I can now say I know the moths of the area as well as anyone. Which is handy for people on the trip, as the main moth books are in Spanish, and many of the moths we´ll see only have a scientific name!
What’s the Spanish word for moth?
The fancy way of saying it is mariposa nocturna which of course translates as “night butterfly”. However I´m trying to bring the word polilla into popular use. It´s a Spanish word for moth, but it actually has negative connotations – it´s usually used to describe the kind of critters that munch their way through your clothes! It makes people laugh when you describe yourself as a moth-studier by using the word polillero, which is why I like it!
Are you excited about running our 2019 Mothing the Straits trip? What does it have in store for the group?
Of course I am! I´ve run loads of successful field courses before, but an actual moth-ing holiday?! As far as I know it´s a first!
Every night we´ll have one or more traps within walking distance of the log cabins at Huerta Grande, plus we will head out into nearby habitats each night to set up another five traps. Each night we will do this in very different habitats within a few miles of our base.
Then we come back for a lovely three course meal of typical local food with plenty of wine and beer!
Then every morning we will head back out to check the traps and this will probably take us the whole morning including photographing the most exciting moths. After that there´s time for picnic lunch, siesta, local exploration, whatever you like, before we set off again in the evening!
The trip actually also coincides with the area´s massive raptor migration. Tens of thousands of Honey Buzzards will be crossing the Straits daily, alongside other raptors like Short-toed and Booted Eagles. I know some of the people that have already booked on my trip are also extending their stay a bit to watch migrating raptors and do some excellent local birding with you two!
Thanks Dave! Sounds amazing! So tell us, where can people find out more about this ground-breaking moth-trapping holiday?
