Spotted coral blenny

I like blennies. They have the kind of goofy expression I see when I look in a mirror. The spotted coral blenny is considered large for the species, growing to 6 inches long. This one was engaged in typical blenny behavior, sitting motionless on a piece of coral.

In my attempts to identify what I see in the water, I use John P. Hoover’s book The Ultimate Guide to Hawaiian Reef Fishes, Sea Turtles, Dolphins, Whales, and Seals. His website is hawaiisfishes.com.

A view of Maui and a wandering tattler

A wandering tattler flies along the Kohala coast on a bright breezy day. What’s notable about this photo is that it was taken in the afternoon and Maui is visible. The reason for that can be seen in the waves. They’re coming from the west to northwest. Waves were from the northeast are driven by the usual northeasterly trades, and those winds would have pushed cloud cover across Maui by this time of day.

A passion vine butterfly lays her eggs

A passion vine butterfly lays an egg.
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.

Abstracts: Morning webs

Webs on the ground catch the early morning sunlight.
I was on the west side of Mauna Kea, at around 7,500 feet, when I saw these lines all over the ground. I don’t know what they are. I doubt they’re spider webs, though they look like it. If they’re trip wires, they didn’t work. But I did like how they caught the early morning sun, which had just cleared the edge of the volcano.

Black stink bug

I thought this was a lady bug when I first saw it, but a bit of research revealed that it’s actually a black stink bug (Coptosoma xanthogramma). Black stink bugs were first found in Hawaii in 1965 on Oahu and can be problematic for some legumes and vines here.
