Di Chris Grinter, on October 4th, 2011 A few months ago a magnificent key to the Lepidoptera of Canada (all of them) was published by Jason Dombroskie – a PhD student from the U. of Alberta. The program is available for windows users only so I haven’t had a good chance to explore it yet – but the PDF is available online and covers the same material. All known Canadian Lepidoptera are included in this key and most of them down to subfamily or even tribe! Esistono 222 taxa, 73 characters and 266 character states that help narrow things down. This is the first reference of its kind to accurately and completely cover the fauna of an entire country and the first to use a well illustrated and interactive key. It’s surprising how well known the leps are yet how few good references exist, almost none of which have a usable key. For everyone out there who has struggled to identify leps before this will be an incredibly helpful resource. Concesso, there are likely a few US moths that could throw a wrench into the flow of things, but by and large I doubt there will be many problems.
Di Chris Grinter, on October 3rd, 2011  Gnophaela vermiculata pair
This Monday moth is an Arctiinae, Gnophaela vermiculata. These beautiful day flying moths were abundant on yellow Helianthus flowers around 9000′ in the Santa Fe National Forest, New Mexico. Caterpillars feed on bluebells, but the adults prefer the highest quality nectar source in the area – which fortunately makes for easy and attractive photo subjects.
Di Chris Grinter, il 30 settembre, 2011 Today marks a sad day in Physics history, gli Tevatron accelerator at Fermi Lab in Batavia Illinois was powered down for the last time. Once the second most powerful accelerator in the world (and most powerful in the USA), the new LHC has made this beautiful machine obsolete. I can only assume the teams of scientists working at Fermi were hopeful for further funding, but the grand ol’ days of big-budget physics was crushed by congress in 1993 with the cancelation of the SSC. Off to Europe our physicists go!
I have many fond memories of visiting Fermi with my grade school science class. Every year Mr. House would take us to explore the physics and nature surrounding the lab. I recall a feeling of privilege when you visited a real working lab where there were no public displays with cute goggly-eyed atoms, just chalk boards full of Feynman diagrams and 3 day old cups of coffee. But it was probably the fully restored big bluestem prairie that grew on and around the 4 mile collider ring was where I had the most fun and is what left a lasting impact on my scientific career.
And so it goes, the evolution of science in the US. I have noticed this particular trend: 1) An active science facility with lots of research has a tiny museum for public tours. 2) The research loses funding and the tiny museum takes over. 3) The museum is renovated to be more “famiglia” friendly and “interactive”, while science is pushed into the basements. 4) Whatever scientists are left (or students hired to act like scientists) are put under glass for the public to watch like strange creatures; all while true research fades into memory.

Di Chris Grinter, il 30 settembre, 2011 Il 2011 Ig Nobel ceremony took place yesterday at Harvard’s Sanders Theatre. Il premio è sponsorizzato da Improbable Research, un'organizzazione che raccoglie affascinante, strano, e documenti di ricerca assolutamente esilaranti che trionfano sull'idea che non tutta la scienza è noiosa. Among this year’s distinguished recipients was fellow entomologist and blogger David Rentz, who received the IgNobel in Biology for a discovery made in 1983 with colleague Darryl Gwynne in the Australian outback. Much to their surprise a certain style of brown bottle with indentations at the base (“stubbies”) proved to be irresistible to males of the Buprestid beetle Julodimorpha bakewelli Julodimorpha saundersii (vedere source paper and comment below).
Congratulations Dave and Darryl!

The microscopic insect world is a very different one from ours and we rarely are given glimpses into it. Thanks in part to the impressive Phantom camera system and the Flight Artists project researchers have filmed the minute (1mm!) Trichogramma wasp (Chalcidoidea) in flight. These insects are egg parasites of Lepidoptera (amongst other groups undoubtedly) and can be used as effective biocontrol agents. As you’ll see in the video it’s been long understood that these wasps hitchhike on adult Lepidoptera waiting for fresh eggs, but it wasn’t know how they got there and if they were even flying onto the adult hosts. Stunningly, this wasp flaps its wings at ~350 times per second to achieve some astounding feats of movement. The biomechanics of this wing mechanism must be fascinating.
Scroll ahead to 1:07 and watch the interaction of the two wasps – the one that flips off to the left of the screen moves in such a bizarre way it looks like bad CGI. I sure hope they record more species of minute flying insects!
Di Chris Grinter, on September 19th, 2011  Trosia nigrorufa (Megalopygidae)
This Monday moth is a stunning female of the Neotropical Megalopygidae – Trosia nigrorufa. Ed Ross and Ev Schlinger collected this specimen in Peru in 1955, and I’ve heard many stories about these epic expeditions. I can’t really imagine travelling via cargo ship, being gone for six or more months at a time and relying mostly on hand written correspondance. It must have made the world feel like a much larger place than it is today.
Di Chris Grinter, il 13 settembre, 2011 This is a pretty epic fail. Immagino che “giovane adulto” le linee guida per la pubblicazione sono meno rigide “fatti”.
Thanks to Richard Lee Brown for first posting this on Facebook.
Di Chris Grinter, on September 12th, 2011 Oops, I skipped last monday’s moth, so here are two! These are some stunners from the CAS Philippines expedition and I think I have figured out their names. If you know better, please correct me.
 Parasa darma (Limacodidae)
 Parotis marginata (Crambidae)
Di Chris Grinter, il 4 settembre, 2011  escluso Samuel
Abbiamo visto tutti questo giorno arrivare, l'ascesa delle farfalle, il giorno in cui si vendicheranno di noi. Non voleranno più passivamente intorno ai loro habitat poiché vengono demoliti per i centri commerciali e inquinati dal deflusso. One particularly angry Karner Blue has submitted a letter to the Onion warning us that our time is about up. Endangered little Lycaenidae will join hands and come after us some quiet night while we’re asleep in our beds. We at the Lepidopterists’ Society have even made their list for failing to take action. Together we should act before it is too late – let us preemptively strike before the rise of the blues. Save your families! Burn those styrofoam containers, pave the prairies, drive your off-road vehicles and take a stand against these fluttering fanatics!
(or we could just save them…)
Di Chris Grinter, on August 31st, 2011 There has been a continuing discussion over the last few years of why so few women remain in science. While I’m not going to dive into that topic here, you can find great discussions qui, qui, qui e qui. I don’t however think anyone argues about why women don’t enter science in the first place, especially when you see things like this. Way to print that soul crushing stereotype right on the front of your daughters shirt, JCPenny.
