New butterfly evolutionary study is out as preprint! 2244 spp sequenced for 391 genes. Butterflies likely originated in what is now Americas, ~100 million years ago. Research led @FloridaMuseum #McGuireCenter. Global study w/87 scientists from 28 countries tinyurl.com/7ra5uaba

発表しました！いろんな蛾が超音波を出す！ヤガ、ヒトリガ、スズメガ、シャクガなど。毒を持つことを超音波を出して敵のコウモリに知らせている。音を擬態する無毒の蛾もいる。私達が書いた科学論文はこちら👇夜行性の昆虫は面白い！biorxiv.org/content/10.110…

地球上の昆虫が急激に減っている。今週、世界中の学者がまとめてPNASに論文を13紙発表した。私は近年の昆虫の減少を止める8つの方法について書いた。この方法に取り組むことで、昆虫の減少を抑制することが出来る。８つの方法: #1. 庭を様々な野生の生息地にする。(2-8 続く)👇pnas.org/content/118/2/…

Another gorgeous moth to celebrate #NationalMothWeek . Eye-tailed moth, Sematura luna (Sematuridae). Eye wing marks likely to fool birds, twisted tails likely to fool bats. Photo by @BiodiversiLary

Very excited to find this awesome rhinoceros beetle! Check out the horns! #Ecuador Golofa sp.

Very cool paper published today in @PNASNews showing that scales on #moth wings can absorb #bat #ultrasound pnas.org/content/early/…

とても綺麗な日中飛ぶヒトリガ。メキシコの高山でしか見られない。Princely Tiger moth, Chrysocalis prinicpalis (Arctiinae).

One of Darwin’s Hawkmoths, on my hand yesterday. #AmazingInsects

夜間採集。大量の蛾だ。昨夜 - Costa Rica, Monteverde. #Lepidoptera #insects

Day 4, #NationalMothWeek . Today's #moth is Uropyia meticulodina (Notodontidae). Check out the visual illusion! Head points to the left and wing pattern makes it look like a curled leaf! Photo: W.-C. Chang @Moth_Week

Day 2, #NationalMothWeek! Here's a vid I took of an amazing wasp moth. Yes, it's a moth, not a wasp! Pseudosphex ichneumonea (Erebidae), Costa Rica @Moth_Week

プラチナコガネを見つけた!!! 体はピカピカの銀色、脚は紫色に輝く。素晴らしいコガネムシだ。今朝、コスタリカの森の中1500mで。 (Chrysina chrysargyrea)

Did you know? We wouldn’t have *Chocolate* if it weren’t for insects? The Chocolate Midge #fly (Theobroma cacao) is the main pollinator of the cacao plant. No chocolate if it weren’t for this little fly! #SaveInsects #NatureEducation

Our study on #butterfly #evolution, #hostplants & #ranges is now formally out! We built a phylogeny of 2000 sp and found butterflies originated in N. America 100M years ago, likely fed on legumes. ~100 scientists from 28 countries contributed. Thanks all! nature.com/articles/s4155…

New paper is out! By @anapscarvalho and others - new phylogeny of butterfly family Pieridae (whites and sulphurs) showing diversification is correlated with global temperature @FloridaMuseum biorxiv.org/content/10.110…

知っていましたか? 皆様の大好きな*チョコレート*は昆虫がいるからあるものなのです。南米に住む小さなハエ（Theobroma cacao）がココアの花に受粉することによってココアとチョコレートが作れるのです。昆虫を守ろう！

Wow! Very cool research, #Hawkmoths lay more eggs on plants that are already damaged by #beetles! Moths hone in on a chemical that is released when prior insect damage occurs. sciencedirect.com/science/articl… photo: Mohammed Salman. Thanks @BarberLab for the heads-up

Day 7, #NationalMothWeek. Moth of the day is a tiger moth that "floats" its pupa in air and creates a golden silk basket around itself to protect against predators. Fascinating defense behavior! Photo: J. Horstman. #moth_week @Moth_Week

Moths are amazing! An incredible tailed moon moth in flight, captured by @braiello . Look at the amazing twisted tails behind the moth. Gorgeous!

新しい鱗翅目の系統論文を#PNASに書いた。蛾は役3兆年前にトビケラから進化し、蝶は1兆年ほど前に昼間飛ぶようになったことが化石と遺伝子を使って分かった。pnas.org/content/early/…
