Maiapilo

Maiapilo (Capparis sandwichiana) is an endemic plant that requires little water once established and is also salt tolerant. This means it grows well on the dry side of the island along the coast. This of course is also an area popular with humans, both for living and recreation. Consequently, maiapilo is considered an at risk plant.

Its standout feature is the beautiful white flowers, but if you want to see them, bring a flashlight or be prepared to get up early. Maiapilo blooms at night and begins to wilt early in the morning, fading to pink as it does so.

These photos were taken around nine in the morning and the bees were busy exploring and pollinating the flowers. At night though, native moths are the main pollinators, attracted by the white flowers and pleasant lemon scent. A cucumber-like fruit follows the flowers but, unlike them, it is said to have a very pungent smell.

The plant can be low-growing and sprawling, or a more upright shrub reaching 10 feet.

Praying mantis egg sacs

When I’m out walking, I rarely see praying mantis egg sacs. They’re no more than an inch long and they can blend in with the trees and branches where they tend to be found. However, on a recent walk on the coast, I saw these three sacs in the space of 20 minutes, the top two on branches and the third on a tree trunk.

I’m not sure why they caught my eye, though this is the time of year when they’re typically seen. Perhaps it was because I was watching for butterflies and dragonflies, so was paying a bit more attention to details than usual.

Each sac can contain up to 300 eggs. The eggs are encased in foam, called ootheca, which hardens into the sacs seen here. The sac in the middle photo was crawling with ants, which I suspect is not good news for the would-be mantises inside.

Kiawe trees (Prosopis pallida) are native to the northeastern corner of South America. They were introduced to Hawaii way back in 1828 and now are the dominant tree in coastal areas on the drier west side of this island. The downside of this is that the tree has wicked thorns that penetrate tires and footwear. My feet have been jabbed through Teva sandals and Adidas hiking shoes. The most popular footwear in Hawaii are slippahs (flip-flops or thongs), but one has to be brave and vigilant, or maybe foolish, to wear those where kiawe grow.

On the plus side, the tree’s wood is popular for firewood and barbecues. Kiawes also provide shade and have light yellow flowers which are popular with bees and butterflies such as the painted lady butterfly in this photo.

Phalaenopsis Minho Princess orchid

This Phalaenopsis Minho Princess orchid was at Hawai’i Tropical Bioreserve & Garden. The garden has been closed for almost a year now because of the Covid-19 pandemic. I haven’t seen any indication of when it will reopen though it will undoubtedly do so when conditions are right.

Common waxbill

Common waxbills are an African species and were first seen on Oahu in the 1970s. Now they’re present on other islands including the Big Island. Lately, they’ve been snacking on the cane grass seeds that are currently available here.

And now for something completely different

The current Friendly Friday challenge theme is ‘Something Different.’ See more responses here.

I think in my 6+ years of doing this blog, I’ve posted exactly one black and white photo. So a selection of black and white scenes seemed like a suitable response for this challenge.

The top photo is of morning clouds scudding over Mauna Kea as seen from the top of Pu’u Wa’awa’a. Second is a shot of surf crashing against an old wharf in North Kohala and, yes, I was secretly hoping the man on the wharf would get soaked! Third is a tenacious tree on the coast near Kawaihae. The bottom photo shows a small fishing boat in the ʻAlenuihāhā Channel, as seen from the North Kohala coast.

Feed the birds

This week’s Sunday Stills challenge theme is ‘Feed the Birds.’ See more responses here.

In the top photo, this ambitious juvenile black-crowned night heron snaffled a tilapia from a large backyard pond. However, that was the easy part. I watched it for quite a while, trying to swallow the fish. It flew from the pond into a tree, then on to another one, before returning to the ground beyond some rocks. The fish was still in its beak, but no closer to reaching its stomach.

In the middle photo, a house finch chows down on the fruit of a tree heliotrope (Tournefortia argentea).

In the bottom photo, a palila feeds on a mamane (Sophora chrysophylla) seed pod. Typically, a palila will grab a pod from one place and then take it to another branch to eat it. It pins the green, immature seed pod to the branch, as in this photo, and then bashes away at it with its powerful beak. The seeds are poisonous, but palilas have developed an immunity to the toxins. The brown pods in this photo won’t be eaten by palilas. They will remain on the tree for a long time before dropping and hopefully producing more trees, though mamane seeds have quite low propagation rates.
