Firethorn Tree (Pyracantha) ピラカンサ（常盤山査子）

英語の後に日本語が続きます。

The firethorn or pyracantha is native to an area extending from Southwest Europe east to Southeast Asia and can be found across Japan. The plant produces beautiful white flowers from April to May and red, orange, and yellow fruits from November to January. 

Firethorn trees in Japan usually are 1 to 2 meter tall but they can reach up to 5 meter tall. I once saw such a tall tree (2nd photo) several years ago but the tree was removed because of the redevelopment of the surrounding area, which is sad but often happens in Central Tokyo.

White-Banded Hunter Hawkmoth (Theretra Oldenlandiae) セスジスズメ（背筋雀）

英語の後に日本語が続きます。

I've seen the black caterpillars in autumn for the last several years. They're caterpillars of the impatiens hawkmoth or white-banded hunter hawkmoth and can be found across Japan. The caterpillars are (kind of) cute but the adults are cool, looking like fighter aircrafts.

Japanese Chestnut (Castanea Crenata) 日本グリ（和栗）

英語の後に日本語が続きます。

The Japanese chestnut (Castanea crenata) is native to Japan and Korea and can be found across Japan. Chestnuts are used for many dishes in Japan, not only sweets but also mixed rice or kuri gohan. 

There are the following types of chestnuts according to Adachi Otoemon, a confectionery shop in Kyoto: 

• Japanese chestnut (Castanea crenata)
• Western chestnut (Castanea sativa)
• Chinese chestnut (Castanea mollissima)
• American chestnut (Castanea dentata)

I know all of them are sweet so I want to taste them all to decide which is the sweetest😋!

Orange Sweet Osmanthus (Osmanthus Fragrans Var. Aurantiacus) キンモクセイ（金木犀）

英語の後に日本語が続きます。

Orange sweet osmanthus (Osmanthus fragrans var. aurantiacus), a variety of sweet osmanthus, is native to China and came to Japan in the 17th century. As its name suggests, the flowers are so fragrant that orange sweet osmanthus is designated as one of the three most fragrant flowers in Japan together with winter daphne and cape jasmine.

The orange sweet osmanthus has been propagated from cuttings in Japan because only male plants were imported to Japan.

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.

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.

ガマズミ（莢蒾）です。東アジア原産で日本中で見られます。花期は春。実は秋に生ります。最初の頃は酸っぱいのですが、秋が深まると段々甘くなるそうです。

花言葉は「愛は死より強し」なかなか強烈です。

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.

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.

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.
