Lunedi Moth

RISPOSTA: Questo non è stato facile – ma questa grande e bella falena era dall'Australia ed è nella famiglia Xyloryctidae (Philarista sp.). We have a handful of representatives of this group here in the US and Ted MacRae over on Beetles in the Bush has a few great photographs of them. Somehow I think we . . . → Per saperne di più: Lunedi Moth

Lunedi Moth

Chiricahua multidentati (Geometridi)

Falena di questo Lunedi è una specie spettacolare delle montagne dell'Arizona – Chiricahua multidentati, un Geometrid. La posizione unica conosciuta per questa specie è in cima delle montagne Chiricahua di cui sopra 9,000 piedi (che è stato appena bruned per un croccante). Hopefully the fire was not . . . → Per saperne di più: Lunedi Moth

I’ll keep the ball rolling with Arctiinae and post a photo today of Ctenucha brunnea. This moth can be common in tall grasses along beaches from San Francisco to LAalthough in recent decades the numbers of this moth have been declining with habitat destruction and the invasion of beach grass (Ammophila arenaria). Ma . . . → Per saperne di più: Lunedi Moth

I’m going to keep the ball rolling with this series and try to make it more regular. I will also focus on highlighting a new species each week from the massive collections here at the California Academy of Sciences. This should give me enough material forat least a few hundred years.

Richard Branson è un idiota

Si scopre che Richard Branson ha una nuova idea; per salvare il lemure dalla coda ad anelli (lemure catta) by importing them to his private British Virgin Island. Come l'articolo sottolinea Branson ha speso milioni di sterline e anni di sforzi per trasformare l'isola in “the most ecologically . . . → Per saperne di più: Richard Branson è un idiota

Mystery Revelaed

Ok – a few apologies for not having full images *yet* of the larvae in question (I will in a few days!). Over the weekend I was out with a group of Berkeley students on Mount Hamilton and PhD candidate Meghan Culpepper collected a few species of Scaphinotus and a some larvae! So the specimen . . . → Per saperne di più: Mystery Revelaed

Estimates of Global Species Diversity

This recent article in the American Naturalist has taken a second look at some of the famously inflated species estimates, some going high as 100 million (Erwin, 1988). Estimates conducted by the authors indicate that projections above 30 million have probabilities of <0.00001. Their estimated range is more likely to be between 2.5 e . . . → Per saperne di più: Estimates of Global Species Diversity

Parte Aquamoth 3

A continuation of the aquamoth series, this time with video from Science Friday! Sì, I have to link it because wordpress won’t embed… Grazie Ted, figured it out!

Parte Aquamoth 2

Mi sono imbattuto il full-text PDF dell'articolo falena anfibia e estratto l'albero che mostra la radiazione di questo gruppo di specie e probabile evoluzione delle caratteristiche anfibie. Interessante notare la forma del caso, e ogni falena è endemica al proprio vulcano dell'arcipelago hawaiano.

Aquamoth!

Another amazing animal from Hawaiia completely amphibious caterpillar (published in the March 22 PNAS). While there are a few aquatic Lepidoptera, all of them have gills that keep them restricted to the water (mind you, we are talking only about the larval stage). If their stream dries up, so does the caterpillar. . . . → Per saperne di più: Aquamoth!
