Door 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 . . . → Lees meer: Maandag Moth
Door 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 feet (which was just bruned to a crisp). Hopefully the fire was not . . . → Lees meer: Maandag Moth
Door 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). Maar . . . → Lees meer: Maandag Moth
Door Chris Grinter, on June 20th, 2011% Ik ga de bal aan het rollen houden met deze serie en proberen het regelmatiger te maken. Ik zal me ook concentreren op het uitlichten van elke week een nieuwe soort uit de enorme collecties hier in de California Academy of Sciences. Dit zou me genoeg materiaal moeten geven voor… minstens een paar honderd jaar.

Het blijkt dat Richard Branson heeft een nieuw idee; aan de ringstaartmaki besparen (Makicatta) door ze te importeren naar zijn privé British Virgin Island. Zoals het artikel wijst erop Branson bracht miljoenen ponden en jaren van inspanning om het eiland te veranderen in “the most ecologically . . . → Lees meer: Richard Branson is een Idiot
Door Chris Grinter, op 6 april, 2011% OK – een paar excuses voor het *nog* niet hebben van volledige afbeeldingen van de larven in kwestie (Ik zal over een paar dagen!). In het weekend was ik met een groep Berkeley-studenten op Mount Hamilton en promovenda Meghan Culpepper verzamelde een paar soorten Scaphinotus en een paar larven! So the specimen . . . → Lees meer: Mysterie onthuld

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 en . . . → Lees meer: Estimates of Global Species Diversity
Door Chris Grinter, on April 1st, 2010% A continuation of the aquamoth series, this time with video from Science Friday! Ja, I have to link it because wordpress won’t embed… Thanks Ted, figured it out!
Door 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 . . . → Lees meer: Aquamoth part 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. . . . → Lees meer: Aquamot!
