Shower time

An Hawaiian Garden Spider in the rain

I saw this female Hawaiian Garden Spider scooting up a strand of her web during a welcome rain shower. She stopped just before reaching the top and was soon the recipient of drops of water dripping from the roof. When the rain passed, she carried on up to the gutter.

I think she was getting some water to drink and possibly enjoying having a little wash. It’s been very dry here lately and water has been in short supply for the local wildlife.

What’s going on here?

The house where I live is ready for Halloween thanks to the generous numbers of spiders living around it. By the front steps, there’s a small Hawaiian Garden Spider and several crab spiders.

One day, I came home and saw a wasp flying close to the various webs. I thought it was dicing with danger, but soon saw that wasn’t the case. Instead, it would approach a web and bob its head toward the spider. It didn’t seem to be a terribly threatening act, though perhaps it was from the spiders perspective. The wasp didn’t push home an attack, but would instead fly away, settle for a bit, and preen itself.

The garden spider didn’t seemed to be bothered by the attention, but the crab spiders would drop suddenly on a strand of silk, before returning to their web as soon as the wasp moved on. I watched these maneuvers for five or ten minutes before heading inside. No webs were damaged, no spiders hurt, and I still don’t know what was really going on!

There’s something bugging me

This week’s Sunday Stills challenge theme is ‘Let’s Get Small.’ See more responses here.

Sorry to start off (above) with spiders, for those with aversions to them, but this one is very small. It’s a tiny female Hawaiian Garden Spider, probably no more than a quarter-inch across, though if it survives, it will grow to be as big as the other one in the photo.

In the gallery below, a Seven-spotted Ladybug putters about in some very green leaves. Another spider, this time a jumping spider no bigger than the little one at the top, has jumped a moth bigger than itself. Finally, what I think is a hover fly pretending to be a wasp with its black and yellow markings.

Finally, a Camponotus variegatus ant or carpenter ant. Next, a bee collecting pollen on an agave attenuata. Note the tiny aphids sharing the flower. And finally ants and aphids on the leaf of a Hawaiian Crown Flower. In this symbiotic relationship, the aphids produce sweet goodies for the ants to eat and the ants provide protection against the aphids’ predators.

Hawaiian Garden Spiders

Hawaiian Garden Spiders and their webs

I noticed that in the front border of the house, the ferns and Mother-in-Law’s Tongue or Snake Plant (Sansevieria Trifasciata) needed weeding and cutting back as there was foliage up against the house, a handy highway for ants and centipedes and who knows what else. The only problem is that, at this time of year, this little garden is guarded by a wall of spiders.

These three Hawaiian Garden Spiders are just a few of that kind there, and they’re accompanied by the usual mass of crab spiders and one or two others I’m not familiar with. I wouldn’t mind moving the crab spiders, whose main activity seems to be to build webs in places that mean they’ll end up wrapped around my head. But the garden spiders, I have a soft spot for. The females are quite beautiful and the males, while drab and tiny, are very watchable as they try to mate with the mighty females.

I guess the weeds can wait for another week or two.

Baby centipede

Centipedes have a modified pair of front legs behind the head, through which they inject their venom, so they don’t really bite, but sting. I have yet to be stung by a centipede, he says tempting fate, but I’m told that it’s extremely painful regardless of the size of the centipede.

This little centipede, which I was happy to spot outside the house, was probably no more than an inch long. But I was taking no chances and ushered it away from the house without getting too up close and personal.

Lesser Brown Scorpions (Isometrus maculatus) are small, shy, and mostly active at night. This is why I’d only seen two here before. One was dead in a box, flattened by the items I was unpacking. The other was alive, but not well. It looked like it had been stepped on.

These photos are of my third encounter, which happened recently. I was getting rid of accumulated odds and ends in the office at work, when I opened up a large, yellow bag that had been stowed there for a year or so. When I looked in, I saw this very much alive and active scorpion.

I took the bag outside, grabbing my camera on the way, and then tried getting some photos, with the help of others in the crew. It was hard to get anything decent because the scorpion scurried around seeking cover. We decided to tip it out onto the tiles. This made the process a bit easier, though not because the scorpion settled down any. It was just as active and every time I looked in the viewfinder it seemed to be making a beeline for me!

After a while I ushered it off the tiles and it scurried away, under the lanai. And while it looks imposing in these photos, it was less than two inches long overall. I’ve read that the sting of these scorpions is similar to a bee sting and not dangerous unless a person is allergic to the toxins. I didn’t feel a need to find out for myself.

Spider on a red door

When I first saw this spider on the front door, I thought it was a small Hawaiian Garden Spider. But after it had been there a while I got a closer look and realized it was something else and that it wasn’t going to get any bigger. I don’t know what kind of spider it is, and I don’t know if it’s going to survive there, since I’ve never seen it catch anything, but I like the shadow it casts on the door.
