A late stage Purple Emperor caterpillar perfectly mimicking half a Sallow leaf - the veins even line up. Fully fattened and about to perform the miracle of pupation, converting to a liquid soup in the pupa and then reassembling into a magnificent butterfly - amazing.

A great article on the potential for native bees in urban areas - this is one of the reasons that we have been experimenting with migratory beekeping with native stingless bees at the Australian Parliament. www.smh.com.au/environment/...

🐙🌿🐍🐛 Nope, it's not a snake - it's the caterpillar of a sphinx moth (Hemeroplanes sp.)., found by our guides in Corcovado Natl. Park., Costa Rica. Normally the caterpillars blend with the vegetation, but if disturbed they twist their head upside down to reveal a "snake," and even wave around to--

I see some people posting their strawberry moon photos from last night, so here is my humble contribution. Micrathena clypeata, sometimes referred to as the strawberry spider, is seen here spinning her moon-like egg sac. This is one of the photos from WildSumaco that I am most proud of.

Top of my list of missing native species we should be looking at reintroducing to Ireland? Lynx!! • Never attack people • Rarely attack livestock • Aren't pack animals • Help regulate deer • Help regulate smaller predators, like fox • Are a huge tourist draw • Are just GORGEOUS!!

3 paddocks west of Melbourne could be Australia's "most important" property. While it's worth millions to developers, it's also home to the only known population of Victorian grassland earless dragons. Experts are worried it's not adequately protected. au.news.yahoo.com/secret-hidde...

Do you have any papers that you keep coming back to, not because they are groundbreaking or revolutionary, but because they are so cool, so well-written and so well-done, basically examples of the kind of science we can all aspire to? I'll start with this one. doi.org/10.1111/1365...

Our paper about the flow of nocturnal bird migration through Colombia is finally out today in #ProcB! Using weather radars operated by the #IDEAM, we found that low variability in wind underlies a pace of migration that is far more gradual than at temperate latitudes. #Ornithology 📡🪶🇨🇴 🧵1/10

I never cease to be amazed by the "Queen of the Night" - the Sonoran Desert's night-blooming #cereus (Peniocereus greggii) - and how nearly all the desert's plants orchestrate a synchronous bloom. The whole deserts' worth of naturally growing cacti all bloomed last night!
