A jumping spider snags a meal

A jumping spider catches a parasitic wasp.
I was watching some butterflies recently when my eye was caught by something tiny (we’re talking a quarter-inch long here) bouncing across the dirt in front of me. I peered down and snapped a couple of photos before it disappeared. I’d seen enough to recognize it as a spider and the photos, while not great, were good enough to enable me to identify it as a striped lynx spider, a kind of jumping spider.

Not long after that, I was again watching butterflies and other bugs inhabiting a mock orange hedge, when I saw this little creature. Again, no more than a quarter inch long, it’s movement caught my eye against the glossy green of the mock orange leaves. A different kind of jumping spider, it hung around, enabling me to get this photo, because it had latched on to what I think is a parasitic wasp. Jumping spider don’t make webs, they pounce on their prey.

Jumping spiders are in the family Salticidae, but there are numerous species within the family and I haven’t yet been able to identify which this is. A characteristic of these jumping spiders is the pair of large eyes in front. This gives them very good eyesight, useful in identifying prey.

Another thing I’ve found out is that they’re everywhere around here. Now that I’m aware of them, and looking out for them, I see them often where I had never noticed them before. Mine eyes have been opened to the glories of the jumping spider – or something like that.

A passion vine butterfly lays her eggs

I watched this passion vine butterfly flitting around on a hedge, laying eggs atop the leaves of, you guessed it, a passion vine growing in the hedge. Typically, she deposits a single egg on each leaf, but this butterfly laid two on this one.

The butterfly is selective about which leaves to use. She chooses ones that have no eggs on them yet, since this will reduce the competition for her offspring. On the leaf she’s using in the photo are some yellow spots. I thought these might be where eggs had been laid previously, but some passion vines produce these colored bumps to make it look like eggs are already there and thus discourage the butterfly.

Not that laying eggs on unoccupied leaves guarantees survival. I saw a number of small parasitic wasps checking out the yellow bumps on several leaves. I have no doubt they do the same with the real eggs. I also saw a very small passion vine butterfly caterpillar snacking on what looked suspiciously like a newly-laid egg. And there’s always the possibility that someone will come along and trim the hedge. Not sure what the vine or the butterfly can do about that.

Humpback whale breach

I could wish for the humpback whales to be around all year, but perhaps that would not be for the best. Aside from the minor detail that they would starve to death here, there’s also so the chance of becoming jaded. As it is, seeing a humpback breaching – raising its huge bulk out of the water and then crashing back in – continues to be a thrill every time I see it.

Truck stuck

While I always prefer to take smaller, winding roads, such roads taken are not without pitfalls.

The last mile of the journey to Mo’okini Heiau in North Kohala is an uneven dirt road studded with rocks. When the road is dry it can be navigated by almost all vehicles (I saw a smart car there once!). However, care is needed, particularly regarding clearance. Almost every time I walk the road, I see fresh scrapes on the rocks. With rainy weather, the road becomes the territory of 4-wheel drives and jacked-up suspensions.

On this day, the puddles that often form on the road had become lakes. This truck had passed me earlier and when I saw it returning I ducked behind a bank to do a little whale watching and avoid the wave of spray that would surely accompany anything driving through the lake. A few minutes passed. I realized I hadn’t registered the truck passing. It had gone very quiet. So I wandered out to the road again and saw the truck marooned. They’d made it through on the way out, but weren’t so lucky on the way back.

The truck was a 4×4 but not with extra clearance. I think their problem was that the lake was deeper at the far end (in the photo). On the way out, they’d no doubt barreled into the water and their momentum had carried them to shallower waters and out. On the way back, the same approach would have propelled them toward the deep end. I suspect a bow wave built up, slowed them, and allowed water to penetrate parts of the truck that responded unfavorably.

The two young local men seemed quite cheerful. They waded through the muddy water, tried to coax life into the truck. One was on the phone (a miracle to have service there). After they insisted they had everything under control, I walked past on the high bank alongside the road, then turned and took this photo. When I returned a half hour or more later, the truck and its occupants were gone.

A flowery flounder vanishes

Camouflage is a creature making a good match with its surroundings. This serves to conceal it from both predators and prey. In the water, there are many exponents of this approach, from octopuses to scorpionfish.

Flatfish are masters of camouflage. It’s a fluke to see a stationary flatfish. It’s almost always necessary to see one on the move and to track it to where it settles down. Once it’s set though, it will usually stay put, making it one of the easier fish to observe and photograph.

I saw this flowery flounder on the move but once it plopped onto a rock (above) I would never have noticed it had I not known it was there.

Bright-eye damselfish

The aptly-named bright-eye damselfish is a tiny fish around 1 to 2 inches long. Despite its small size it aggressively defends its territory, usually a nook or hollow in the rock. It’s not unusual to see it come charging out at some much larger fish that has strayed too close.

Given that these fish spend all their time in one small area, often just hovering in the water, it would seem a simple matter to get a photo, but no. When they hover, they’re constantly moving, almost vibrating. And then they shoot off in one direction or another.

I’ve taken many of photos of bright-eye damselfish and the majority of them turn out to be pictures of bits of rock or coral. Locating the tiny fish on my screen is no easy matter, keeping it there, harder still. When I do manage that, often the fish is a blur or just a tail fin heading out of shot. Thus, this photo is something of an against-the-odds triumph – an entire bright-eye damselfish reasonably in focus.
