赤い頭がちょっと毒々しいこの虫はヤマイモハムシと思われます。英語の common name はおそらくないです (それらしき物が書かれたweb siteを一つ見つけたんですが、添付されていた写真があまりにも別のハムシだったので自信がないです)。学名は Lema honorata。これもおそらく日本固有種です。なんとハムシ科の仲間は日本に約570種もいるそうです。もしこのハムシがヤマイモハムシでなかったらすみません。それにしても昆虫の種類の多さには目を見張る物がありますね。
I found a insect that have a red head. Probably, this is "Yamaimo hamushi" that means "yam leaf beetle". Scientific name of this leaf beetle is Lema honorata. It is probably native in Japan. This time, I don't have solid confidence, since there are 570 kinds of leaf beetles in Japan. If it's not "Yamaimo hamushi", I'm sorry. Anyway, the variety of insects are really amazing!!!
ムラサキシラホシカメムシの幼虫を見ました。背中に２つある白い点が見分けるポイントです。幼虫には白い点の下に白い横線がありますが、成虫になるとこれがおそらく羽で隠されて見えなくなるようです。これも日本固有種のようで、英語の common name はないようです。学名は Eysarcoris annamita。なんか白い2つの点が目のようで、白い線が口にも見えますよね。
I found a nymph of "Murasaki sira hoshi kamemusi" that is endemic in Japan. "Murasaki sira hoshi kamemusi" means "violet weevil with white stars". I don't think that its is violet though. It does not have an English common name. Its scientific name is Eysarcoris annamita. We can distinguish this weevil from other weevils by two white stars on its back. Its nymph has a white horizontal line under the two dots, while its adult does not have. The two white spots look like eyes and the white line look like a mouth a little bit, aren't them?
お尻の先が白いアブを見つけました。シオヤアブ (塩屋虻) と言うようです。お尻の先の白い部分を塩に見立てた命名だとか。どうやら日本固有種のようで、英語の common name はないようです。学名は Promachus yesonicus と言うそうです。
I found a fly that has white on tip of its tail. Its Japanese name is "Sioya-abu" that means a fly that sells salt. Hmm. The white region looks like salt a bit!? It seems that the insect is endemic in Japan. There is no English common name. Scientific name of this fly is Promachus yesonicus.
なんか泥まみれに見えるゾウムシを見つけました。でも何回かおそらく別個体を見かけて、すべて泥まみれに見えるので、別に本当に泥にまみれているのではなく、これが本来の姿のゾウムシのようです。もし地面にいたら、完璧な保護色になりますね。このゾウムシの名前はスグリゾウムシというようです。英名はtwobanded Japanese weevil。Weevil とは「ゾウムシ」という意味です。学名はPseudocneorhinus bifasciatus Roelofs。英名にJapaneseが付いていますが、日本だけではなく、中国、韓国、モンゴル、そして東シベリアにもともと生息していたようです。今ではアメリカでも外来動物として生息圏を広げているようですが。ただし、遠くまで自ら移動できる訳ではないので、人間が植物を移動する時にくっついて広がっているようです。ちなみにスグリゾウムシは単為生殖をするので、アメリカでは雄は見られないそうです。雄は日本では男女群島女島と言う限られた島にだけおり、あと中国でも雄がいるそうですが、やはり雌の数の方が圧倒的に多いようです。面白いですね！
I found a beetle that looks like covered in mud. But I saw several same looking weevils. So it is actually not covered in mud, it is the natural look. Japanese name of this insect is "Suguri-zoumusi" and English name of this insect is two banded Japanese weevil. Although English name has Japanese in it, it is native to China, Japan, Korea, Mongolia, and eastern Siberia. It is now established in the eastern United States, and occurs in New England, the mid-Atlantic states, Indiana, and Illinois. Its presence in Florida was confirmed in July 2005. As the weevil is flightless, it is unlikely to spread to long distances by jumping, and a pattern of dispersal in this manner is not evident in the mapped records of the southeastern region (Wheeler and Boyd 2005). Therefore the spread in the southeastern states is possibly due to the movement of infested ornamental plants. Twobanded Japanese weevils reproduce parthenogenetically, and males are generally not encountered in the United States although they are known to occur in China. In Japan, we can find males of this insect in only very limited place. Females are dominant in most of places in Japan. It's very interesting, isn't it?
I took this picture at the end of May and had been wondering what it is. I finally found the name of this plant. The name of this plant is Ribwort Plantain or English Plantain. Scientific name is Plantago lanceolata. Japanese imported this plant during Edo period (1603-1867). I think that this plant looks like a firework little bit.
In my pond, Dense water weed (alternative names are Large-flowered Waterweed or Brazilian Waterweed) are growing. I found white cute flowers of the water weed. It is native to South America. Japan imported this plant as a scientific material. Now, we see the plant invading everywhere in Japan.
こちらがオンブバッタの幼虫。ショウリョウバッタの幼虫とだいぶ違いますよね。肉眼で見ると、オンブバッタの成虫の小さいバージョンでかわいらしいんですが、カメラを覗くとびっくり。成虫ととても質感が違いますよね。カメラって肉眼で見えないいろいろな事を写してくれるのでとても楽しいです。オンブバッタの英名は、smaller longheaded locust。ショウリョウバッタ (longheaded locust) の小さい版という安易な命名です。学名は Atractomorpha lata というそうです。
This insect is a nymph of smaller longheaded locust. Scientific name of this locust is Atractomorpha lata. Japanese name of this locust is "onbu batta" that means piggyback ride locust, since when it becomes adult, males are often on females, even when they are not mating. The texture of the nymph is very different from the adult. It is very difficult to see its texture by the eye, but the camera enable me to see the texture. Camera is great!
I found a good article about this locust in English. So I cite the article. Original article is from the Japan times (Click here).
* Japanese name: Shouryou-batta * Scientific name: Acrida cinerea antennata * Description: Although it is called the long-headed locust, this member of the grasshopper family of insects has a stranger appearance than the more familiar swarming locust. "Shouryou" refers (bafflingly) to the Buddhist word for the spirit of the dead, while "batta" means grasshopper. It has hugely long hind legs, and the body is 4-5 cm long in males, 7-8 cm long in females. The head is very long, sharp and triangular, tipped with two long antennae. This grasshopper comes in two color types, green and brown, but the head shape never leaves any doubt in identifying the species. * Where to find them: In grass, all over Japan, in summer and autumn. Long-headed locusts are often found in vacant lots around houses, but they are even more commonly heard. The insect rubs the inner surface of its hind legs against the outer surface of the forewings, making a "chiki-chiki" sound that accounts for its other name of chiki-chiki batta. * Special features: Females are bigger than males because they lay a large mass of eggs, surrounded in a foamy, protective substance. Eggs take more energy to produce than sperm, so females are bigger. In both sexes, the stilt-like hind legs are specialized to store energy like a coiled spring. This energy can be almost instantaneously unleashed if the insect is startled, and the sudden kick propels the animal away. Grasshoppers grow by molting, and just before and after the final molt to adulthood, the exoskeleton is soft and weak. This means that kicks cannot be performed with the same power, lest they damage the exoskeleton. Instead, the insect kicks by conventional muscle contraction, rather than releasing stored energy. After about two weeks the body is strong enough not to be damaged by kicking; the locust modifies its kicking behavior until its body is strong enough to cope.
My parents have an interesting plant named "Ko dakara so" that means a plant that have many children". As you can see, its leaves have many buds. The buds drop on earth and start to grow. Scientific name of this plant is Bryophyllum 'crenatodaigremontianum', since this plant is a hybrid of B. crenatum (Kalanchoe crenata) and B.daigremontianum (daigremontiana). This plant is sometimes also called Kalanchoe 'crenatodaigremontianum' . Anyway, it is interesting and the buds are cute.
ハラビロカマキリの幼虫達が庭でぐんぐん大きくなっています。とっても綺麗な写真が撮れたので up します。一概に虫好きと言っても、人それぞれ favorite は違うと思います。私はなんと言ってもカマキリですね。これってホント、理屈ではないです。ハラビロカマキリの学名は Hierodula patellifera Serville。東南アジアに生息しているカマキリです。相手を威嚇する時に、おしりをピンと上げるのが特徴です。赤ちゃんのうちから親と同じようにおしりを上げるので、とってもかわいいです。産まれたときの3倍くらいに大きくなりましたが、ぜひ無事に成虫になって欲しいです。
In my garden, a kind of praying mantis, Hierodula patellifera Serville, is growing. Japanese name of this mantis is "Harabiro kamakiri" that means a praying mantis that have a wide belly. This praying mantis even small nymphs bends its belly upward, when it comminates. I like the behavior. It distributes southeast Asia. I love praying mantis. The emotion is beyond logic. I'm just so attracted by the insect.
"Oo-shiokara-tonbo" that is a beautiful blue dragonfly in Japan came to my pond. I was crouching beside the pond. The dragonfly was checking me for a while and seemed like it thought that I was not dangerous. Then it perched a branch of a tree. I was able to get close to the dragonfly. Since it was not scared of me, I felt a kind of affection (strange?). Scientific name of this dragonfly is Orthetrum triangulare melania. It is native to Japan and south China. Since it comes around this season, I feel like this dragonfly brings summer.
Do you know tiger beetles? Japanese name is "Hanmyo". It has another Japanese name, Michi-oshie, that means insect that tell you a direction. This name is derived from their behavior. This insect flies away when people get close to the insect, and then lands in front of people. So people feel like they are following the insect. There are many species of tiger beetles. Among these tiger beetles, I saw Cicindela kaleea yedoensis (Japanese name is Tokyo Hime Hanmyo) that is native to Tokyo, Japan. Wikipedia says that some tiger beetles can run at a speed of 5 mph. For its size it has been suggested that they are technically the fastest running land animals. This has been featured on "Animal Planet's Most Extreme" show as the number one fastest animal known to man on earth. Hmm. Really?
Now flowers of Nerium oleander are blooming beautifully in my gaedem. Japanese name of this plant is "Kyou-chiku-to". It is native to a broad area from Morocco and Portugal eastward through the Mediterranean region and southern Asia to Yunnan in southern parts of China. Japan imported the plant from India. Oleander is one of the most poisonous plants and contains numerous toxic compounds, many of which can be deadly to people, especially young children. The toxicity of Oleander is considered extremely high and it has been reported that in some cases only a small amount had lethal or near lethal effects. They are present in all parts of the plant, but are most concentrated in the sap. Oleander is also known to hold its toxicity even after drying. It is thought that a handful or 10-20 leaves consumed by an adult can cause an adverse reaction, and a single leaf could be lethal to an infant or child. According to the Toxic Exposure Surveillance System in 2002 there were 847 known human poisonings in the United States related to Oleander. Wow. I did not know that. There are many cases not only in the US, but also in Japan, France, and Australia. In many cases, victims used the plant as skewers for BBQ. Please be careful!
