Conopid Fly

From a my morning walk a few days ago: conopid fly Conops vesicularis (Diptera: Conopidae). These seem to be quite variable in the color and extent of the dark markings on the thorax and abdomen: in some the markings are black, in others reddish brown; in some they extend less than half-way down the abdomen, in others they go right to the tip. However, the dark triangular markings on the wings, and the relatively long antennae seem characteristic of this species.  The reddish form is similiar to, but a bit larger than, Sicus ferrugineus which I saw several times last year.  The larvae are parasites of bees nests.

Rust Fly

A rust fly, Psila fimetaria (Diptera: Psilidae).  Rather distinctive markings on the top of the thorax, which I didn't notice at the time I took the photo.

Clouded Silver Moth

A clouded silver moth, Lomographa temerata (Lepidoptera: Geometridae).

Why 'clouded silver'?  I would have thought 'clouded white' more appropriate.

Sawfly

A woolly alder sawfly, Eriocampa ovata (Hymenoptera: Tenthredinidae), so-called because its larvae are woolly and live on alder trees.

I photographed another adult at about the same time last year but, at the time, I mistakenly thought it was a Eutomostethus ephippium.   However, the latter have more red down the sides of the thorax, and their antennae are thicker (compare this with this).
