Urban wildlife in Scotland: 11 insects and 1 spider
Marcel van Oijen
This website recently hosted pictures of vertebrates in our Edinburgh garden. This time we show some of our favourite arthropod visitors. Unlike the vertebrates, which we see year-round, insects in Scotland are easiest to spot in the summer, followed by spiders in autumn. The following pictures were taken between mid-July and mid-September.
When we walk on the grass in summer, we see small bits of straw rising up and landing a meter or so away. Those are Straw Grass Moths (Agriphila straminella), one of the 2500 moth species in the UK. Grass moths are micromoths of about 1 cm length. When they land on the grass, they immediately freeze and allow themselves to be photographed from up close:
Once or twice a year we put out the moth trap to see what lives in our garden. The trap is just an open box with a lamp above. The moths fly toward the light and hide in the box, allowing us to admire them the next morning. Mornings are relatively cold, so most boxed moths hesitate to fly away even when we carefully take them out and take pictures. It is still not fully clear why moths are drawn to artificial light, but flight analysis suggests they treat lamps and natural light sources in the same way . We see Orange Swift Moths (Triodia sylvina) quite often. They are doing well, populations are increasing and expanding further into Scotland, but they are yet to reach Ireland.
Scalloped Oak Moth is another common species (Crocallis elinguaria):
There are 57 species of butterfly in the U.K. of which 35 breed in Scotland. We see Comma butterflies (Polygonia c-album) more and more each year:
There are two insects in this picture! Notice the huge size difference between the Buff-Tailed Bumblebee (Bombus terrestris) and the Highland Midge (Culicoides impunctatus). The cute little midge is the reason why we don’t go wild camping in the Scottish Highlands in the summer, but in Edinburgh they are still fairly rare:
This is the most common hoverfly species in the U.K. (Helophilus pendulus):
The Peacock (Aglais io) is found all across Eurasia, and we see it very often. It is beautiful (but we like the moths more):
Like many larger butterflies, the Red Admiral (Vanessa atalanta) lets itself easily be photographed if you slowly move toward it, staying as low as you can:
The macromoth species that we see the most is the Large Yellow Underwing (Noctua pronuba). You can see that this one is nearing the end of its lifetime:
I find it difficult to take pictures of flies, so was happy to see this Common Siphona Fly (Siphona geniculata) land on the flower that I had just focused on:
The Eyed Ladybird (‘Ladybug’ in American) (Anatis ocellata) is one of the prettiest aphid-eaters:
And this is the only spider for today: a subadult of the Lesser Garden Spider (Metellina segmentata). Seeing it is a sign that autumn has come:
