Fireweed control moth

The fireweed control moth (Secusio extensa) was deliberately introduced from Madagascar in 2012 because its larvae feed on fireweed. Unlike many other introductions, the moth was first confined to a study area to make sure it would not wreak havoc on native species. Having passed that test, it was released into the wild.

I’m not sure how much impact the moth is having on the fireweed, but I think it’s a pretty and quite striking moth.

Hawaiian garden spiders face off

Hawaiian garden spiders face offHawaiian garden spidersThis pair of Hawaiian garden spiders spent a long time facing off from different sides of the female spider’s web. The male is the smaller, drab spider, while the larger female has splashes of yellow, orange bands on her legs, and a bejeweled back, which can be seen here. The female spiders are much bigger than the males, though this female is not actually a particularly large one. Full-sized females dwarf their male counterparts.

I don’t know how this encounter turned out, but the previous day I did see another male on this web and it did not turn out well for him. I didn’t get good photos, but he appeared to be thoroughly enveloped in her ‘loving’ embrace.

When male garden spiders approach a female, they pluck the females web in a certain way to alert her to their presence. Typically, successful male garden spiders mate with a female and then die immediately afterwards. Sometimes the female will eat their male suitors. I’ve read than canny males will try to mate while the female is undergoing her final molt because during this process she will be immobile!

Passion vine butterfly

A passion vine butterfly feeds from blue heliotrope flowers. What I liked about this was the lower image where the passion vine butterfly has spooked a lesser grass blue butterfly into flight. It made me think of the Hank Williams song, Move It On Over, and in particular the line, ‘Move over little dog cause the big dog’s moving in.’

Psamatodes abydata moth

The psamatodes abydata moth is also known as macaria abydata. Its common name is dot-lined angle moth. The moth was first introduced into Hawaii in 1970 and became established on all the main islands by 1984.

This one was perched on the window of a vehicle, giving it that splendid blue background and cool reflections.
