Potato Vine (Solanum Laxum) ツルハナナス（蔓花茄子）

英語の後に日本語が続きます。

The potato vine (Solanum laxum) is native to South America, came to Japan during the Taisho era (1912-1926) for ornamental purposes, and can now be found across Japan. Its Japanese name is "tsuru hana nasu," which translates into "vine flower eggplant," after the resemblance of its flowers to those of eggplants. Eggplant or potato? It's so confusing.

Loquat (Eriobotrya Japonica) 枇杷（ビワ）

英語の後に日本語が続きます。

The loquat (Eriobotrya japonica) is native to China, came to Japan from the 6th to 8th century and is now grown in warm regions, such as Nagasaki and Chiba prefectures. The plant produces flowers from November to February and fruits from May to June. The fruits are orange and shaped like a Chinese lute or pipa (枇杷), which is why the plant is called "pipa" in Chinese while "biwa" in Japanese, both are written in the same Chinese characters but pronounced differently. Although the flowers are plain, the fruits are so orange, and sweet and juicy that the trees in my neighborhood produce many fruits every year but I've never had a chance to taste them.  

By the way, loquats always bring back fond memories of my childhood.

When I was a second-grader, I lived in a town in southern Japan where there were many wild Amanatsu orange and loquat trees. One day my baby brother and I decided to go on a loquat picnic - just the two of us. I got up early and prepared lunch boxes, and after breakfast, we left home for a place with many loquat trees a few kilometers away. As soon as we got there, we started picking these orange fruits, and after that, had lunch there while talking about the harvest that day, i.e., about 20 fresh big loquats, and brought them home.

Looking back, however, something is bugging me. Were these loquat trees wild? Might they be planted trees in a loquat farm? I remember a couple of people there staring at us, not saying anything.

Now I'm pretty sure that that was a loquat farm and they were loquat farmers who were kind and generous enough to let local kids pick the loquats they'd grown without saying anything. I no longer remember exactly where that was, but these orange round fruits always remind me of this small adventure.

Scarab Beetle 黄金虫（コガネムシ）

英語の後に日本語が続きます。

Scarab beetles are quite prevalent and familiar to people in Japan. Actually, there's a song titled "Scarab beetles are rich." The lyrics are based on the lyricist (Ujo Noguchi)'s childhood memories that cockroaches gather in rich people's houses as they're warm and have food and that at that time, cockroaches were called "kogane mushi," which translates into "scarab beetles" in English😆!

Scarab beetles can be highly destructive to lawn and gardens. The adults feed on foliage and flowers, while their underground larvae damage the root systems of turf grass, ornamental plants, and crops. Scarab beetles, however, are so beautiful and their sleeping posture is funnily acrobatic (scroll down).

Sphaerophoria ミナミヒメヒラタアブ（南姫扁虻）

英語の後に日本語が続きます。

Philadelphia fleabane (Erigeron philadelphicus) is native to North America, came to Japan in around 1920, and can now be found across the country. Actually, the plant is so prevalent as a weed that they're called "binbo gusa" and "binbo giku" in Japanese, which translates into "poor plant" and "poor chrysanthemum" respectively in some areas in Japan. On a Philadelphia fleabane is a tiny hoverfly. It's so tiny but very beautiful.

I've been growing herbs recently but this is mainly to use them for cooking but I realize I can enjoy them aesthetically, so I put monk's cress and oregano flowers, and mint in a glass.

Small Branded Swift (Pelopidas Mathias) チャバネセセリ（茶羽挵）

英語の後に日本語が続きます。

The small branded swift can be seen in east Asia and Oceania. The butterfly resembles the common straight swift very much but the small branded swift has white spots in a circle while the common straight swift (Parnara guttata) has such spots in a straight line.

Small Copper (Lycaena Phlaeas) ベニシジミ（紅小灰蝶）

英語の後に日本語が続きます。

The small copper (Lycaena phlaeas) flies from March to November in Japan, so it's not unusual to see them but it was my first time to see them, not one but two! Their orange forewings caught my eye. The butterfly's coloration changes slightly across seasons; spring broods are typically brighter while summer ones become darker and more muted. I can't say for sure but one of them seems like a spring brood and the other a summer one. Scroll down to see the two together in a photo.

Aromaticus (Plectranthus Amboinicus) アロマティカス

英語の後に日本語が続きます。

The aromaticus (Plectranthus amboinicus) is primarily native to Southern and Eastern Africa and has been seen in Japan since the 2000s. I've taken an early morning walk for more than five years and this is my second time to find herbs growing wild on the sidewalk.   

The one I found for the first time was apple mints. I took several stems home and have planted them in a pot. The incredible resilience of herbs always makes me feel motivated and energized.
