Kanadako lepidopteroen giltza

A few months ago a magnificent key to the Lepidoptera of Canada (denak) was published by Jason Dombroskie – doktorego ikasle bat U. Albertakoa. Programa Windows erabiltzaileentzat bakarrik dago eskuragarri, beraz, oraindik ez dut arakatzeko aukera onik izan – 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! Badaude 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. Onartua, 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.

Gnophaela vermiculata pair

 

This Monday moth is an Arctiinae, Gnophaela vermiculata. These beautiful day flying moths were abundant on yellow Helianthus flowers around 9000in the Santa Fe National Forest, New Mexico. Caterpillars feed on bluebells, but the adults prefer the highest quality nectar source in the areawhich fortunately makes for easy and attractive photo subjects.

Gaur Physics historian egun triste bat markatzen, du Tevatron accelerator at Fermi Lab in Batavia Illinois was powered down for the last time. Munduko bigarren azeleragailu boteretsuena Behin (eta boteretsuenak 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 oldays 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 “familiari” friendly andinteractive”, 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.

Tevatron at Fermi: Reidar Hahn/Fermilab

Sexy, Garagardo botila sexyak

The 2011 Ig Nobel zeremonia ospatu zen atzo Harvard Sanders antzokian,. The award is sponsored by Improbable Research, an organization that gathers fascinating, odd, and outright hilarious research papers that triumph the idea that not all science is boring. Aurtengo hartzaileei bereizten artean ikaskide entomologo eta blogger zen David Rentz, IgNobel jaso biologian batentzat aurkikuntza egin dira 1983 lankide Darryl Gwynne Australiako desertua batera. Euren harridurarako askoz botila marroi estilo jakin bat oinarrian indentations batera (“Stubbies”) frogatu liluragarria izan Buprestid kakalardoa, gizonezkoak Julodimorpha bakewelli Julodimorpha saundersii (ikusi source paper eta behean).

 

Zorionak Dave eta 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 waspsthe 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!

Asteleheneko sitsa Megalopygidae Neotropikoko eme harrigarria da – Bihurtu nigrorufa. Ed Rossek eta Ev Schlingerrek bildu zuten ale hau Perun urtean 1955, eta istorio asko entzun ditut espedizio epiko hauei buruz. Benetan ezin dut imajinatu zamaontzian bidaiatzea, aldi berean sei hilabete edo gehiago joan eta eskuz idatzitako korrespondentzian oinarrituz. Mundua gaur egun baino askoz leku handiagoa sentiarazi behar zuen.

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.

Plebejus samuelis

We all saw this day coming, the rise of the butterflies, the day they will take vengeance on us. No longer will they passively fly around their habitats as they are bulldozed for malls and polluted with runoff. 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 LepidopteristsSociety have even made their list for failing to take action. Together we should act before it is too latelet 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…)

Emakumeen Zientzietan

Ez dago etengabeko zergatik emakume hain gutxi zientzia jarraituko dute azken urteotan eztabaida bat izan da. Ez naiz bitartean hemen gai horretan murgiltzea joan, you can find great discussions hemen, hemen, hemen eta hemen. Ez dut ordea uste inork zergatik emakumeek ez zientzia sartu lehenik eta behin buruz argudiatzen, especially when you see things like this. Way to print that soul crushing stereotype right on the front of your daughters shirt, JCPenny.
