Crab spider webs and fruit

Crab spiders (also known as spiny-backed spiders) came to Hawaii in 1985. They spread through all the islands and are especially numerous here in the winter months. They build dense thickets of webs such as these between two tangerine trees. They look threatening, but aren’t particularly. People do get bitten, mostly if a spider falls on them or gets lodged in clothing.

I usually encounter them when I miss spotting a web and end up with it wrapped around my head. Their webs, which often span a 10 or 20 foot gap, seem especially strong and sticky.

Cuckoo wasp

I saw this small, bright insect flitting about on the new growth of a plumeria. The cuckoo wasp gets its name from its practice of laying eggs in the nests of other wasps and bees. Once hatched, the cuckoo wasp eats the host wasp or bee larva. Then it eats the food placed in the nest for the host’s offspring. Probably not an insect to invite to your next dinner party.

Abstracts: Where’s the dragonfly?

Dragonfly in a kiawe tree

I was walking through a stand of kiawes when a dragonfly jitterbugged by. I hoped it might loop back so that I could get a photo of it, but instead it headed toward the top of a tree and disappeared. I thought I saw where it went and got as close as I could, which was still a good distance away. I trained my camera in its direction and took a few photos, not sure if it was even in shot. I thought I might just be taking pictures of a twig. It wasn’t until I got home and looked at the photos that I saw I’d been right about its location all along.

Yellow-billed cardinal

Yellow-billed Cardinal
030916-951-Yellow-billed-Cardinal-HWA South American bird, the yellow-billed cardinal was introduced to Hawaii and is quite common on the Big Island. I saw these two birds flitting through a stand of kiawes. The bird in the top photo was working hard on the bit of foliage in its beak. I assumed this was something for a nest, but didn’t see where the bird went. The second bird just hung out in the trees, possibly keeping watch.
