Με τον Chris Grinter, on August 15th, 2011% ANSWER: This wasn’t easy – but this large and beautiful moth was from Australia and is in the family 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 . . . → Διαβάστε περισσότερα: Δευτέρα Moth
Με τον Chris Grinter, on August 1st, 2011% Chiricahua multidentata (Geometridae)
This Monday’s moth is a spectacular species from the mountains of Arizona – Chiricahua multidentata, a Geometrid. The only known location for this species is at the very top of the Chiricahua mountains above 9,000 πόδια (which was just bruned to a crisp). Hopefully the fire was not . . . → Διαβάστε περισσότερα: Δευτέρα Moth
Με τον Chris Grinter, on July 18th, 2011% 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 LA – although in recent decades the numbers of this moth have been declining with habitat destruction and the invasion of beach grass (Ammophila arenaria).

Με τον Chris Grinter, on June 20th, 2011% 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 for… at least a few hundred years.

Με τον Chris Grinter, on April 6th, 2011% Εντάξει – 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 . . . → Διαβάστε περισσότερα: Αποκαλύφθηκε το μυστήριο

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 και . . . → Διαβάστε περισσότερα: Estimates of Global Species Diversity

Με τον Chris Grinter, on March 25th, 2010% I came across the full-text PDF of the amphibious moth article and extracted the tree showing the radiation of this species group and probable evolution of the amphibious traits. Interesting to note the case shape, and each moth is endemic to its own volcano in the Hawaiian archipelago.
This is a Bayesian analysis of . . . → Διαβάστε περισσότερα: Aquamoth μέρος 2

Another amazing animal from Hawaii – a 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. . . . → Διαβάστε περισσότερα: Aquamoth!
