Common Straight Swift (Parnara guttata)　イチモンジセセリ（一文字挵）

英語の後に日本語が続きます。

Butterflies usually fold wings when resting while moths with open wings. The common straight swift (Parnara guttata) is a butterfly but sometimes rests with open wings to absorb the warmth of the sun, thanks to which I've learned that their back is green (in the 1st and 2nd photos). The 3rd photo is of an ant carrying a dead common straight swift.

The common straight swift is called "ichimonji seseri" in Japanese, meaning "straight line skipper" after its white spots in a straight line while small branded swift (Pelopidas mathias), which has white spots in a circle, is called "chabane seseri," meaning "brown wing skipper."

Greater Death's Head Hawkmoth (Acherontia Lachesis)　クロメンガタスズメ（黒面形天蛾）

英語の後に日本語が続きます。

I believe this is a caterpillar of a bee robber or greater death's head hawkmoth (Acherontia lachesis). I've seen many caterpillars and always find it difficult to know what it is but this is an easy one because of its size.

A larva of the bee robber is as long as 10 cm - 12 cm and changes its color. The caterpillar in the photo is on a stem with its head on top. Its Japanese name is "kuromengata suzume," translating to "black face hawkmoth" after a black (or skull) face on its thorax. Unusually, its English and Japanese names coincide, which makes me want to see its adults.

Plains Cupid (Luthrodes Pandava)　クロマダラソテツシジミ（黒斑蘇鉄小灰蝶）

英語の後に日本語が続きます。

Plains cupid or cycad blue (Luthrodes pandava) resembles pale grass blue. Both are beautifully shiny blue gray on the upper side. One of the distinct differences between the two (I can tell) though is that the former has an orange spot on the underside.

Their existence has been confirmed in Japan since the 1990s to 2000s and now can be found almost across Japan.

Pink Clematis　ピンクのクレマチス

英語の後に日本語が続きます。

There are various types of clematis in terms of color, the number of petals, and whether single or double-flowered. These are single flowered pink clematis with only four petals. Clematis can be found across the globe. They generally flower from spring to autumn but some flower only once a year while others everblooming.

This clematis had only two flowers, suggesting its being near the end of flowering season.

Linden Arrowwood (Viburnum Dilatatum) 　ガマズミ（莢蒾）

英語の後に日本語が続きます。

Linden arrowwood (Viburnum dilatatum) is native to Eastern Asia and can be found across Japan. It produces white flowers in clusters from April to June and also clusters of red drupes in autumn. The drupes are too sour to eat in the beginning but become sweeter towards late autumn.

The linden arrowwood means that "love is stronger than death" in Japanese floriography.

Mealycup Sage & Maile Pilau Hornworm　サルビア・ファリナセア & ホシホウジャク

英語の後に日本語が続きます。

Mealycup sages (Salvia farinacea) are native to North America and Mexico. They're perennial there but annual in Japan. Hovering over them are burnt-spot hummingbird hawkmoths (Macroglossum pyrrhosticta). Surprisingly to me, they're not bees or wasps but moths. I've seen them many times, but they move from one flower to another so swiftly that I had no chance to photograph them. Today, however, while I was taking photos of the sages, hawkmoths came to the flowers, luckily giving me the chance to take pictures of them. Their larvae's host plants are skunkvine.

Lespedeza (Bush Clovers)　萩（ハギ）

英語の後に日本語が続きます。

Bush clovers are native to East Asia and can be found across Japan, flowering from July to September. The term "bush clover" is a kigo, i.e., a seasonal word or phrase associated with a particular season used in traditional forms of Japanese poetry, for autumn, but Lespedeza actually flowers from early summer to autumn.

Bush clovers are known to produce pink flowers but they also have white flowers (Lespedeza buergeri) and some (Lespedeza japonica bailey cv. versicolor) produce pink and white flowers on the same tree.

White Early Amethyst (Callicarpa Japonica F. Albibacca)　コシロシキブ（小白式部）

英語の後に日本語が続きます。

This is white early amethyst (Callicarpa japonica f. albibacca). I've seen early amethyst, which is purple, many times and photographed them through the year from buds to flowers and to fruits but saw white fruits for the first time.

Early amethyst is native to Asia and can be found across Japan. It produces flowers in clusters from July to August and tiny drupes also in clusters from September to November. Its Japanese name is "koshiro shikibu," meaning white "komurasaki," which translates to "small East Asian beautyberry" because early amethyst and East Asian beautyberry resemble each other but the former is smaller than the latter.

The Japanese names of early amethyst and East Asian beautyberry both contain "muraski," which means purple and Murasaki Shikibu or Lady Purple. Lady Purple is a Japanese novelist, poet and court lady at the Imperial court in the Heian period (794 - 118), known as the author of The Tale of Genji, which is often said to be the world's oldest long novel.

Red, White, and Yellow Spider Lily (Lycoris)　ヒガンバナ（曼珠沙華/彼岸花）

英語の後に日本語が続きます。

Spider lilies are native to China but can be found across Japan. They flower in September and therefore are called "Autumnal equinox flower" in Japanese. Spider lilies are known generally as red flowers (Lycoris radiata) but they produce white (Lycoris albiflora) and yellow (Lycoris traubii) flowers. A white spider lily is not a sibling of a red one, but a cross-breed of a red and a yellow spider lilies. It's interesting that a child of red and yellow flowers is white.

A yellow spider lily is called "Shouki zuisen" in Japanese, translating to "Zhong Kui lily" as its petals look like the beard of Zhong Kui, a demon hunter and Chinese deity who fights ghosts.

Despite their beauty, red spider lilies are associated with death in Japan for an unfair but understandable reason. Although cremation is the most popular now, burial used to be common in Japan and therefore red spider lilies were planted to keep moles and other animals away from bodies because the plant's bulbs are poisonous. Spider lilies are called "higan bana," meaning "flowers during the higan period." "Higan" is a Buddhist holiday, i.e., three days before and after both the Spring equinox and Autumnal equinox.

Early Amethyst (Callicarpa Dichotoma)　コムラサキ（小紫）

英語の後に日本語が続きます。

Early amethyst (Callicarpa dichotoma) is native to Asia and can be found across Japan. It produces tiny pale pink flowers in clusters from July to August and tiny drupes also in clusters from September to November. The fruits are green at first and then turn purple. (Scroll down!!) Its Japanese name is "komurasaki," which translates to "small East Asian beautyberry" because the two resemble each other but the former (i.e., early amethyst) is smaller than the latter.

Their Japanese names both contain "muraski," which means purple and Murasaki Shikibu or Lady Purple. Lady Purple is a Japanese novelist, poet and court lady at the Imperial court in the Heian period (794 - 118), known as the author of The Tale of Genji, which is often said to be the world's oldest long novel.

Auaxa Sulphurea　キエダシャク（黄枝尺）

英語の後に日本語が続きます。

The summer is finally over this year and signs of autumn are here in Tokyo, one of which is the return of butterflies and moths. This is Auaxa sulphurea, one type of geometer moth. If it hadn't moved, I would have thought it was a leaf.

Auaxa sulphurea is seen across Japan and also Taiwan and can be easily identified by the horizontal brown red line. The caterpillars feed on plants usually in the rose family, known to mimic a rose twig.
