Longhorn Moth

From back in spring-time: longhorn moth Adela fibulella = Cauchas fibulella (Lepidoptera: Adelidae) on germander speedwell (Veronica chamaedrys), the food-plant of its larvae.

Deception between Carrion Crows

Yesterday I witnessed some very human-like behaviour between two of our local carrion crows (Corvus corone):

I was looking out of our kitchen window, which is on the second floor, and initially saw only one crow down on the lawn. This crow was holding something white in its beak, maybe a piece of bread. Suddenly, it looked around, and then poked a hole in the ground, popped the white thing into the hole, and then picked up a leaf and placed it over the hole. At that point a second crow flew down from the roof of our flat, landing on the lawn a couple of metres from the first crow.  The first crow slowly walked off to one side while the second crow walked in a round-about way to the exact spot where the first one had stood.  The second crow then picked up the leaf, laid it to one side and poked around in the hole.  Having apparently satisfied itself as to the contents of the hole (it didn't appear to eat the contents), the second crow then replaced the leaf on top of the hole and wandered off.

It seems natural to interpret the first crow's behaviour as an attempt to hide the white thing from the second crow, but what intrigues me is the second crow putting the leaf back after it had a look in the hole.  This seems to indicate an instinct to hide from the first crow the fact that it had had a look.

Longhorn Moth

From back in early July: a female longhorn moth, probably Nemophora cupriacella (Lepidoptera: Adelidae).

These little metallic longhorn moths can be quite difficult to distinguish visually but, fortunately, they tend to appear at different times of the year:

See here for a female Adela reaumurella that I photographed back in May 2010.

Orange Fly

A small orange fly, possibly Neuroctena anilis (Diptera: Dryomyzidae).

[Note added 2012-10-29: This species has apparently recently been renamed back to Dryomyza anilis.]
