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.

Meadowhawks (Sympetrum) 赤とんぼ

英語の後に日本語が続きます。

I've taken photos of blue dragonflies, such as blue-tailed forest hawks and white-tailed skimmers, several times but red ones for the first time (though I saw them many times in my childhood). I believe this is a meadowhawks (Sympetrum) but there are many types of meadowhawks and I don't know which one. 

In Japan, there is a very famous song for children titled "Red dragonfly." I don't listen to children's songs almost at all but this red dragonfly made me feel a bit nostalgic.

Star Magnolia (Magnolia Stellata) シデコブシ（四手辛夷）

英語の後に日本語が続きます。

The star magnolia (Magnolia stellata) is native to Japan, flowering in early spring. Its flowers resemble white magnolia (Yulan magnolia) very much, but there are several differences. Star magnolia flowers are star-shaped and a little smaller than white magnolia. The way of flowering is also different, i.e., star magnolia flowers fully open while white magnolias only half open even when in full bloom. 

On 13 September 2025, I found something interesting. A star magnolia tree had several fruits beside another tree with many buds, one of which was half open (4th photo). This is, however, not unusual (at least in Japan). Magnolias are known to flower outside the flowering season due to unusual weather or other reason. This magnolia tree may have produced buds and flowers in September because of the extremely hot summer this year.

Cabbage White Butterfly モンシロチョウ（紋白蝶）

英語の後に日本語が続きます。

I thought it was a common grass yellow butterfly at first but it's not so yellow and its spots, which should be black, are paler or nearly pale gray, which made me conclude it's a male cabbage white butterfly.  

Although its English name and Japanese name (which translates to "spot white butterfly") both include the term "white," the male cabbage white butterflies are yellowish. Also, according to Kubota Corporation's website (in Japanese only), they can tell the male from the female by the wing color because they can see ultraviolet light. The female's wing, which reflects ultraviolet light, looks brighter than the male's wing, which absorbs the light.

Blue-Striped Nettle Grub (Parasa Lepida) ヒロヘリアオイラガ（広縁青毒棘蛾）

英語の後に日本語が続きます。

What do you see in these photos? I thought it was a strange-shaped grasshopper but you know what? It's a moth! A blue-striped nettle grub (Parasa lepida). I found this on the backside of a leaf of a "drunken" Confederate rose tree. It is a native minor pest found in the Indo-Malayan region, including India, Sri Lanka, Vietnam, Malaysia and Indonesia according to Wikipedia and as an introduced pest, it's currently found across Japan now. The adult (this one) is colorful and cute but its larvae have spines that contain venom.

Pagoda Tree (Styphnolobium Japonicum) エンジュ（槐）

英語の後に日本語が続きます。

Cream yellow flowers scattered on the ground made me look up and find a Japanese pagoda tree (Styphnolobium japonicum). 

Japanese pagoda trees are native to China, coming to Japan at the latest in the 8th century, and now can be found across Japan in parks and schools. As you can see in the 4th photo, the Japanese pagoda tree is in the Fabaceae family.

"Drunken" Confederate Rose スイフヨウ（酔芙蓉）

英語の後に日本語が続きます。

These are Confederate roses (Hibiscus mutabilis cv. versicolor) and the first five photos are of one flower, taken at 10:00, 12:30, 15:30 and 16:30, and at 5:30 on the following morning. Because of such a color change from pure white in the morning to pink in the afternoon, this type of Confederate roses is called "drunken Confederate rose" in Japan.

The sixth and the last ones are red and white marbled. Some Japanese apricot trees produce such colored flowers but (I believe that) a Confederate rose tree producing such flowers is quite unusual. White apricot trees don't exist but red ones produce white or red/white marbled flowers when they cannot produce enough anthocyanins to make flowers red. The same may apply to this hibiscus tree. 

If you want to see peach, Japanese apricot, or lespedeza having white, pink/red or marble-colored flowers on a tree, read the following posts: 

- Red & White Marble Colored Flowering Peach

- Half & Half Colored Japanese Apricot (White & Pink)!

- Lespedeza Japonica Bailey cv. Versicolor (Variegated Bush Clover)

Okra (Abelmoschus Esculentus) オクラ

英語の後に日本語が続きます。

I've eaten its fruits numerous times but saw the flowers for the first time. These are okra flowers. Okra flowers resemble Hamabo hibiscuses very much but that's understandable. Both are in the Malvaceae family.

The okra is native to East Africa, coming to Japan at the end of the Edo period (1603 - 1867), and is now used for various dishes, such as salad, tempura, (miso) soup, stew, and saute.

Three Types of Swallowtail Butterflies アゲハ蝶3種

英語の後に日本語が続きます。

There are various types of swallowtail butterflies and these are three of them. Butterflies usually close their wings when resting but are also known to open their wings to bask in the sun to warm their bodies. The first one was like this when being photographed and at that time the temperature was 26°C. Did this butterfly need to warm its body? I don't know.

White-Tailed Skimmer (Orthetrum Albistylum) シオカラトンボ（塩辛蜻蛉）

英語の後に日本語が続きます。

These are white-tailed skimmers (Orthetrum albistylum). The dragonfly is found across Asia and Russia. Males and females can be distinguished by color. Males are bluish while females are yellowish. The thing is young males are also yellowish, which makes it difficult to distinguish young males from females. 

The white-tailed skimmer dragonfly is called "shiokara tombo" in Japanese, which translates to "salty dragonfly" because of a white powdery substance developed on its' abdomen.

Crepe Myrtle (Lagerstroemia Indica) サルスベリ（百日紅）

英語の後に日本語が続きます。

Crepe myrtle (Lagerstroemia indica) is native to China, coming to Japan before the Edo period (1603 - 1867) and can be found across Japan now. The tree produces flowers in various colors, white, pink, and red. Its leaves turn orange and red beautifully in autumn and the dark brown fruits are also beautiful.   

The crepe myrtle has two names in Japan, "saru suberi," which translates to "monkeys slip" because of its slippery bark, on which even monkeys (are said to) slip, and "hyaku jitsu ko," which translates to "red for one hundred days," after that the crepe myrtle flowers bloom for a long period of time.

According to Flower Meanings, the crepe myrtle flower means;
- Prosperity;
- Good luck;
- Chastity;
- Good luck in love and marriage; and
- Marital fidelity.

But here in Japan, it means:

- Eloquence;
- Charm and;
- Carelessness.
