Uma “nuvem” de agúdias “invadiu” a Feira do Livro de Lisboa.
Estes insetos saem com o objetivo de se reproduzirem com insetos de diferentes ninhos e são inofensivos. “As formigas em si não fazem absolutamente nada", esclarece Roberto Keller, investigador de Ciências.

One of the strong points of #TETTRIsEU is the Cascade-grant mechanism. We managed to give 1.8 million € to 12 amazing Satellites projects that are now producing great results and pushing the reach of the project to new limits.
Enjoy L.U.C.E. and the italian #fireflies 👏

I have been worried on the field, and it is not just in Portugal. It has been decreasing immensely since 2013. I have never seen such low numbers as I have last month's field work. Nor such low numbers of species. :/
Everyone is saying the same. Especially whoever goes to the southern areas.

Any entomologists know what these eggs? are that I found in soil in Pittsburgh?

NEW PAPER, JUST OUT! 👀

Insects from the '70s and '80s were already collecting microplastic, decades before the term microplastic even existed. 🤯

A thread on the surprising history of this pollutant and the incredible insect larvae that helped us uncover it. 🐛

Let's dive in! 🧵👇 1/x

As I see my colleagues at risk of job loss in the US government, I have been on the phone with people in tears over many concerns I won’t get into on this platform. I am doing my best for them behind the scenes. However, I will recall a passage from William M. Wheeler in 1970. #science #entomology
It quite saddens me to think that when I cross the Styx, I may find myself among so many professional biologists, condemned to keep on trying to solve problems, and that Pluto, or whoever is in charge down there now, may condemn me to sit forever trying to identify specimens from my own specific and generic diagnoses, while the amateur entomologists, who have not been damned professors, are permitted to roam at will among the fragrant asphodels of the Elysian meadows, netting gorgeous, ghostly butterflies until the end of time.

Snap! Trap-jaw ant (Orectognathus mjobergi) from Australia just caught herself a large collembolan prey. What's interesting here is that the ant has to carry it high up in the air to prevent it from being dragged on the ground and potentially picking up mites, fungi etc'.

Australia has the shiniest ants.

This is a worker of Rhytidoponera aspersa carrying eggs among her colony's nest sites.
A closeup view of an ant whose body is as wrinkled as a raisin, but metallic blue/green/purple iridescent, and with lightly hairy red legs and antennae, walking on brown soil and carrying several whitish oblong eggs.
