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。

Impatiens hawkmoths, also known as white-banded hunter hawkmoths (Theretra oldenlandiae), can be found across Japan. Their caterpillars are a beautiful black, creating a stark contrast with their orange spots initially, before turning brownish prior to burrowing into the ground to pupate. They can also sometimes be pale green, as their body color varies depending on temperature and age. While the caterpillars have a chubby appearance, the adults look cool, resembling fighter jets. Adults can be found from May to October in Japan.

Cherry Caterpillar (Phalera Flavescens) モンクロシャチホコ（紋黒鯱）

英語の後に日本語が続きます。

I couldn't believe my eyes. These are so called cherry caterpillars, larvae of Phalera flavescens or a moth. They eat cherry leaves so voraciously from August to October that some trees cannot survive, which is understandable, because I saw several branches covered by the larvae😱!

But more surprisingly, they're edible and some even say they're yummy😱!!! When roasted over a fire, they are traditionally noted for a subtle, pleasant flavor and aroma reminiscent of cherry blossoms from feeding on cherry leaves. This leaves me with a question. Who tried them first? How courageous the person is for trying them!

I went there on the following day, finding all the branches with the larvae having been removed. I don't know whether to feel glad or sad...

Geometer Moth シャクガ

The moth looks like a small purplish gray (Iridopsis humaria) but it can't. A small purplish gray exists in only North America according to information on the internet.

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.

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.

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.
