Sun continues

While much of the UK has been under water for the past month, I'd hazard a guess that April was one of the driest on record in Co. Donegal. Although we've had a lot of sun, the wind has been easterly and that keeps things cooler.

Butterflies are out and about, though, and I've had Small Tortoiseshell, Speckled Wood, Green-veined White and now Orange Tip.

The male Orange Tip is unmistakeable, with those bright orange wing-tips:

The males emerge a few days before the females in order to establish their territory, which they will defend against any moving white object, including pieces of paper. The females will be out next week and then I'll be looking for eggs on their host plant - Cardamine pratensis.

Green-veined White is usually the first of the spring-emerging butterflies on the patch. The males have fewer black markings than the females:

Here's a shot of the female for comparison:

Interestingly enough, the Orange Tip and Green-veined White share a common foodplant, but whereas the Orange Tip larvae eat the seedpods, the Green-veined White larvae eat the leaves.


Tachinid flies are parasitic on the caterpillars of larger moths, and are readily identified by their extremely bristly appearance:

Judging by the number of Tachinids I encounter, it is clear that they are serious population controllers.

The Clouded-bordered Brindle moth is normally found from late May onwards. This is fully a month early, so the heat has brought the overwintering larvae on a bit more quickly than usual.

The moth above is rather unusually marked: the central white 'kidney mark' is missing. Compare with this one from a couple of years ago. http://donegal-wildlife.blogspot.com/2010/06/busy-time.html



Breaking news: the recent mystery eggs that I showed in Juncus rush appear to belong to a leafhopper, rather than a sawfly. Full details in the next post.
