Sphingids of Spain: Is That a Hummingbird? No, It’s a Hawk-moth!

You might have noticed that we haven’t been blogging very much recently. The reason for this is because we’ve been on the road travelling through France and Spain. Tom cycled 1000 kilometres from Bristol, UK, to Toulouse, France, over eight days to raise money for Pancreatic Cancer UK in memory of his dad. Tom’s mum and I were his support-crew, setting up camp and keeping him fed and watered along the way. We are so proud of him! You can read more here.

Of course, after all that cycling, some well-earned critter-hunting was in order. The two beautiful specimens that will feature in this post and our next post are moths we found in the mountains of the Basque Country, Spain. They can also be found in the UK, so keep your eyes out for them.


Hawk-moths: Family Sphingidae

Hawk-moths are moths found in the family, Sphingidae. The adults are also known as sphinx-moths, and the caterpillars as hornworms (many of the larva have posterior ‘horns’). Their narrow wings, streamlined abdomens, and rapid and manoeuvrable flight are all distinguishing features of the family. Worldwide, there are approximately 1,450 species, of which 17 occur regularly in Great Britain.

The Hummingbird Hawk-moth (Macroglossum stellatarum)

You can see the hummingbird hawk-moth in the UK from April to December, with smaller numbers recorded throughout the rest of the year. They are an immigrant from southern Europe and north Africa. They are widespread throughout UK, but are most numerous in southern and eastern England, south Wales and the Midlands. The amazing thing about this species is how easily they can be mistaken for an actual hummingbird.

The Royal Society for the Protection of Birds (RSPB) says that every year people think they’ve seen hummingbirds in their gardens, when it’s actually a case of mistaken identity. I’ve been caught out by this, too! As we don’t have hummingbird hawk-moths in New Zealand, the first time I ever saw one was when I was living in Japan. I was cycling past a flowerbed in town when I saw it hovering and flitting from flower to flower. I’d never seen a hummingbird before, so I didn’t know what to make of it. I lept off my bike with great excitement to get a better look. That’s when I noticed it’s proboscis probing the flowers for nectar. A day-flying moth that flew and behaved like a bird…. An even more exciting find!

Their resemblance to hummingbirds is a great example of convergent evolution – the process whereby organisms that are not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. In this case, the hummingbird hawk-moth has evolved a body shape, wing movements and flight action that are almost identical the hummingbird. Their wings even make the same humming noise in flight. This is because they have both evolved to exploit the niche of an aerial nectar feeder.

We loved watching the hummingbird hawk-moths feeding on the buddleja. It was such a wonderful sight. Keep your eyes out, and hopefully you can see one, too.
