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…

A really good article that came out today. #Insects are important and many are disappearing from Earth. What should we do? graphics.reuters.com/GLOBAL-ENVIRON…

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…

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

Happy #NationalMothWeek! There are >150,000 species of #moths in the world and many of them are beautiful, important to us + our ecosystem, yet declining. Help save moths by dimming/turning off exterior lights this week. One of the largest is Atlas moth, from SE Asia! @Moth_Week

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

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

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

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…

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！

Very interesting study published today in @CurrentBiology showing that moth wings' ripples may be to lure predatory bats away from their bodies as defense! Moths are just so cool! By @drtomneil, Marc Holderied and colleagues. sciencedirect.com/science/articl…

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

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

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

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

6.昆虫に対する否定的なイメージを払拭する。
7.教育者して昆虫の保護を提唱していく。
8.地域の自治体へ参加し、科学への支援を求める。
皆んなで昆虫保護に協力しよう！

2.在来植物を栽培する。
3.農薬や除草剤の使用を減らす。
4.屋外の照明を少なくする。
5.車の洗浄に使用する洗剤の排水を抑え、車道の防水剤や除氷塩の使用を減らす。
