Lesser grass blue butterflies

Lesser grass blue butterflies

Lesser grass blue butterflies and a spiderThe lesser grass blue butterfly (Zizina otis) was first seen in Hawaii on Oahu in 2008 (for an article, or most of an article, about the find, click here). They’re now well established on the Big Island as well.

Lesser grass blues are very small, with a wingspan no more than ¾-inch. With wings folded up they’re the size of a small fingernail. They also fly close to the ground, within a foot or two.

Lately, I’ve been seeing them in large numbers on these blue heliotrope (Heliotropium amplexicaule) flowers. When I say ‘seeing them,’ what I mean is that when I walk past a patch of these flowers, a host of lesser grass blues will flutter up from the flowers, dance around in a tizzy for a few moments, and then settle back down again. When they do this, it’s like blue confetti being thrown (a few inches) into the air.

I’ve tried to capture this image with my camera, but haven’t been able to (and I’ve taken LOTS of photos). The butterflies are so small, I’m tall, and the effect is fleeting. But the top photo gives an idea of what’s going on, with three lesser grass blues homing in on the small blue heliotrope flowers while a fourth has already found a spot.

It wasn’t until I processed the photos at home that I noticed the spider in the second photo. I don’t know what it made of all the butterfly activity. I hope they weren’t its prey.

Bee on lantana

Bee on Lantana

Lantana is such a colorful flower – pink and purple, yellow and orange (and invasive here, but let’s not talk about that). Curiously, it doesn’t seem all that popular with bugs, at least by my observations. But at certain times I see butterflies very interested and on this occasion, several bees were going from bloom to bloom.

Mongoose alert

Mongoose

On a recent hike at Pu’u Wa’awa’a, I was ambling along one of the trails when I heard squeals and a commotion in the grass a few feet off to the side. A mongoose shot out from cover hotly pursued by a second one. They took off down the trail, away from me, before vanishing into the undergrowth on the other side.

A couple of minutes later, this one reemerged, trotting away on the trail before it turned suddenly and gave me this look. I don’t think my presence had registered earlier, so it must have been a bit surprised to see me. Don’t know what happened to the other one, but since I didn’t hear any horrendous screeching, I suspect it got away.

Indomitable melipotis moth

Indomitable Melipotis Moth female

Indomitable Melipotis Moth male (700)Two photos of indomitable melipotis (Melipotis indomita) moths, a female above and a male below. This species is common across the southern United States, but many sources do not include Hawaii in its range. However, it was first recorded here in 1969 according to this paper (https://scholarspace.manoa.hawaii.edu/handle/10125/11031) published in 1974.

Caterpillars of the moth were first found on kiawe trees but soon after turned up on defoliated monkeypod trees, hence it also being known as the monkeypod moth, because of its fondness for shrubs and trees of the legume family. They’re certainly quite common up here on the northern tip of the Big Island as I see them often when I’m out and about.

Many thanks to Daniel at whatsthatbug.com for help with the identification. For his detailed information about the moth, see https://www.whatsthatbug.com/2018/05/01/indomitable-melipotis-moth-from-hawaii/.

Bryophyllum

Bryophyllum and Pu'u Wa'awa'a

Bryophyllum and beeThis bryophyllum is probably bryophyllum x houghtonii, but there are several similar looking varieties of bryophyllum. Their common names are telling, however. Bryophyllum x houghtonii is known as ‘hybrid mother-of-millions.’ Common names for other bryophyllums include ‘mother-of-millions,’ ‘prolific mother-of-millions,’ and ‘mother-of-thousands.’

Such names make it no surprise that bryophyllums are invasive. They’re also poisonous to both livestock and humans, which is problematic since these photos were taken at Pu’u Wa’awa’a, in an area occupied by sheep and cattle.

Pig dig

Pig Digging

Pig DiggingsOn an early morning hike at Pu’u Wa’awa’a, I saw this wild pig on the hillside above me. It was busy rooting around in the dirt, hence the brown snout. Wild pigs can do an enormous amount of damage in their foraging. The photo at right shows one of many areas alongside the trail that has been dug up by pigs. These areas are susceptible to erosion when it rains.

I was glad the pig was a ways up the hill as the other damage they can do is to people who get too close. Given the size of this one, I suspect I’d have come off second best.

Rosy wolfsnail

Rosy Wolfsnail

The rosy wolfsnail (Euglandina rosea) is a voracious predator. It devours other snails and slugs, and because of this trait, it was introduced into Hawaii in 1955 to control the numbers of invasive African land snails. Unfortunately, the African land snail grows to a very large size and, when it gets that big, the rosy wolfsnail wants nothing to do with it.

Instead, the rosy wolfsnail took a liking to the much smaller indigenous snails and proceeded to wreak havoc on their numbers. It’s now on the International Union for Conservation of Nature’s list of the top 100 worst invasive alien species in the world.
