Elementary, my dear reader

Moth identification is a dark art, and last night a famous quotation from Sherlock Holmes came to mind: "When you have eliminated the impossible, whatever remains, however improbable, must be the truth." 

My version, adapted to Moth identification, is as follows: "In March, when you have eliminated all other possible identifications, then the moth is Clouded Drab, no matter how unlike the specimen is to the usual illustrations."

Clouded Drab - Orthosia incerta

I showed my first Clouded Drab last year in April (Click here to see it), and I'm sure you'll agree there is little superficial similarity between the images. Clouded Drab feeds on many broadleaf plants as a larva.

Another timely moth is the March Moth - Alsophila aescularia, which think is a rather delicate little beast:

March Moth (male)
Yet again, the females of the March Moth are wingless. It seems that there's some correlation between the cold-weather moths and flightless females (although it's not exclusive to them). There must be some advantage  in that system, but I can't quite work it out.

My first Beetle for the year is one of the Chrysomelids, or Leaf Beetles - Chrysolina staphylea. I'm seeing more of these each year since I first recorded it 3 years ago.

The Chrysomelid beetle Chrysolina staphylea

It's about the same size as a 7-spot Ladybird, and they can often be found in the same locations.

Full swing

We've had a few days of sun now, and it's already getting difficult to keep up with the number of species I'm seeing.

Some water-walking insects are revealed by the shadows they project onto the base of the ditch. These 4-leaf-clover-type shadows are made by the water cricket Velia caprai. The insects themselves are present, but are hard to see as they scoot across the surface of the water.

A bit of refocussing (well, a lot really) and the insects themselves are revealed:

This Common Carder Bumblebee - Bombus pascuorum - was nectaring on the Celandine. I'm presuming she's also a queen, although they're a lot smaller than the other local bumblebee queens.

An excellent juxtaposition of two beautiful beetles: 7-spot ladybird and the leaf beetle Chrysolina staphylea:

Plenty more moths are coming to light, although this one didn't quite meet the friend it expected:

This is the Early Grey - Xylocampa areola:


And two colour forms of yet another willow feeder, the Common Quaker - Orthosia cerasi:

10 minute dash

I had only about 10 minutes for my photography session this evening, so I was pleasantly surprised when I looked at my memory card later on.

It took me about 20 minutes to get an identification for this wonderful Leaf Beetle, Chrysolina staphylea.


It's about the same size as a 7-spot Ladybird.


The Orange Tips were roosting for the night. This one's on unfurling Broad Buckler fern :


And this brought a smile to my face. These are the micromoth Micropterix calthella on the bud of Creeping Buttercup. Micropterix calthella feed on Buttercups all summer, and this is the first local flower of the year. They just cannot wait for opening time tomorrow morning.
