Stick insect

A stick Insect rests on a truck tire

One thing I like about macro photography is that, sometimes, something in the photo gives a twist to the scale of things. This stick insect could be any size, but the tire tread suggests it’s fairly small. Except the tread looks so big and imposing, perhaps it’s a tire on one of those huge earth moving machines, which would make the stick insect a formidable size.

In fact, it’s just a truck tire and if the insect doesn’t move, it will become even more closely acquainted with the treads.

Hawaiian blue butterfly

This endemic Hawaiian blue butterfly was flitting around at the Palila Forest Discovery Trail, on the southwest flank of Mauna Kea. This one is, I think, a female with its bright underside and uniformly brown top.

The butterfly is also known as the Koa butterfly, since its caterpillar feeds on that tree. I don’t think Koa trees are found in the trail area, but ‘A‘ali‘i (Dodonaea viscosa), an indigenous Hawaiian plant, does grow there and that’s another plant the caterpillar will eat.

Fruit flies on a mango

Fruit Flies feed on a mango

This week’s posts are in response to the WordPress photo challenge on the theme of ‘transient.’

This little scene could be considered transient on three counts. First is the fact that this is a mango that has fallen from the tree. In the life cycle of a mango, it’s a very short interval between ripening on the tree and rotting on the ground. Second, this mango has clearly been chewed over by one of the transient wild pigs that pass through from time to time, more so during mango season. And third, these fruit flies won’t be around long either, having a lifespan in the region of 30 days.

This fruit fly, also called the vinegar fly, is probably Zaprionus ghesquierei, an invasive species known to have reached Hawaii. Zaprionus indianus also looks like this, but hasn’t been seen in Hawaii yet, as far as I know.
