英語の後に日本語が続きます。

White-tailed skimmers (Orthetrum albistylum) are 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. 

White-tailed skimmer dragonflies are called "shiokara tombo" in Japanese, which translates into "salty dragonfly," after their white powdery substance developed on their abdomen.

Lithocarpus Edulis (Japanese Stone Oak) 馬刀葉椎（マテバシイ）

英語の後に日本語が続きます。

The Japanese stone oak (Lithocarpus edulis) is native to Japan and can be found across the country. The nuts are edible, tasting like chestnuts when baked (according to a website).  

In Japan, the nuts of Fagaceae trees, one of which is the Japanese stone oak, are collectively called "donguri" and there's a famous song for children about an acorn falling into a pond "Donguri korokoro (i.e., Rolling acorn)."    

The tree's Japanese name is "mateba shii," which translates into "a tree becoming a chinquapin tree soon," because people prefer(ed) chinquapin nuts to the Japanese stone oak nuts.

Balloon Vine (Cardiospermum Halicacabum) 風船蔓（フウセンカズラ）

英語の後に日本語が続きます。

The balloon vine (Cardiospermum halicacabum) is native to tropical and subtropical regions, came to Japan during the Meiji era (1868-1912), and is now grown for ornamental purposes across the country. As its name suggests, the balloon vine is known for its balloon shaped fruits but you shouldn't miss its tiny white flowers or dark brown seeds with heart-shaped white spots on them, which are so sweet (scroll down)!

When I was photographing the flowers, the owner came out to give me the seeds. I put them in a pot at home, hoping they come up.

Panicled Hydrangea (Hydrangea Paniculata) ノリウツギ（糊空木）

英語の後に日本語が続きます。

The panicled hydrangea (Hydrangea paniculata) is native to east Asia and can be found across Japan. The hydrangea look to me resembling oakleaf hydrangea (Hydrangea quercifolia), so I often mistook the latter for panicled hydrangeas and this is my first time seeing the panicled one still in bloom. 

The panicled hydrangea's Japanese name is "nori utsugi," which translates into "glue Deutzia," after their inner bark being used before to make a natural adhesive for washi, i.e., Japanese paper, and their stems resembling those of Deutzia.

Yellow Spotted Stink Bug キマダラカメムシ（黄斑亀虫）

英語の後に日本語が続きます。

Eggs of yellow spotted stink bugs (Erthesina fullo) hatch into nymphs as below. 

-------------------------------------------------------------------
Below is a record of 2025/6/12 I found their eggs for the first time.

On 12 June 2025 (scroll down), I found a circle the size of a quarter dollar coin on a leaf of Chinese tallow (3rd photo). Then, five days later (i.e., on 17 June), they'd become like in the 2nd photo and for the last day since then, they have changed like in the 1st photo! Every bug is small but you can clearly see each is a yellow spotted stink bug. They've changed not only their appearance but also have started to move. The one in the upper right of the 1st photo was running toward the backside of the leaf. They may not be there tomorrow, which makes me feel a bit sad and relieved a lot.   

P.S.
On 19 June 2025, I went there again to check up on them, finding them like in the 1st photo. All larvae are all gone but two on the eggs in the 1st photo and one each in the 2nd and 3rd photos.

Fig (Ficus Carica) イチジク（無花果）

英語の後に日本語が続きます。

Fig (Ficus carica) is native to west Asia, came to Japan either in the 1590s through Father Diogo de Mesquita, a Portuguese Jesuit who came to Japan in the 16th century as a missionary, or in around 1630 through China. Its flowers are hidden, growing inside the pear-shaped structure. This is the origin of its Japanese name "無花果," which translates into "no flower fruit." A fig fruit, however, is actually not a fruit but inverted flowers😮.

A fruit of Japanese camellia. Japanese camellia blooms resemble sasanqua camellia blooms very much but their fruits do not. In autumn, this should look like chocolates.
