In the 1850s the export market for Palmeran wine collapsed, and somebody had the bright idea of going into cochineal production. Before the advent of synthetic dyes, this was far and away the best red dye available, particularly for wool. For one thing, it doesn’t fade. Cochineal is made from a parasitic insect (Dactylopius coccus), which lives on prickly pears (tuneras), so the plants and insects were imported from Mexico….
The people who lived here before the Spanish invasion in 1493 were called Benauaritas. Since they didn’t have writing, not all that much is known about them, and what there is comes from the invaders. Not exactly an unbiased source! Their technology was pretty basic, maybe because the climate in La Palma is kind enough not to encourage things like weaving. They wore skins, lived mostly in caves, herded goats…
Yponomenta gigas caterpillars and web. I’d never heard of caterpillars that make cobwebs before, but these do. Like many others caterpilars in the family of ermine moths, they form communal webs. I suppose it discourages birds from sticking their beaks in. My book on Canarian insects doesn’t mention them at all, but then they aren’t easy to find unless you know where to look. They live on the Canarian Willow,…
Every year NASA holds a competition to chose the best photo of Earth. The Canary Islands won this year’s Tournament: Earth is again. (Last year’s winner was a photo of the submarine eruption off El Hierro.) The Canary Islands sit in the trade winds and the Canary current, both of which come from the north east. This photo, taken by NASA’s Terra satellite on June 15, 2013, shows long…
Most of the telescopes at the observatory here look spectacular even from the outside. SuperWASP looks like a big garden shed. It’s the white thing at bottom left. Even when it opens up, it still doesn’t look like a professional telescope. To me, it looks more like a small missile launcher. The equipment isn’t that spectacular either. As modern telescopes go, it was built for peanuts. It has eight cameras,…
cloud waterfall400 Jigsaw Puzzle Because the island sits in the trade winds, damp air hits the northeast of the island and has to rise, where it turns into clouds. Because La Palma has a north-south spine called the Cumbre Nueva, the cloud quite often reaches up to the ridge and then tumbles over as the cloud waterfall. This is extremely pretty, and best viewed from around the western side of…
