Surprise moment

A shimmer of blue, something highly likely in case of a chrysalis that belongs to a Blue and is about to hatch. However, with Blue’s the determination of the species is often tricky. Here’s just another case where I was completely wrong until the very end.

Earlier this year I found two caterpillars of Blues. I expected the caterpillars to be of the Mazarine Blue (Plebeius semiargus). But what eventually hatched was a female Common Blue (Polyommatus icarus). In this case I luckily took one of the caterpillars home. This specifically to be able to get confirmation on the species. Unfortunately, I only took one of the larvae. To be absolutely sure both were the same species I’d have had to raise each of them.

Caterpillar kick-off

It took quite some time this spring to find the first caterpillar due to very cold weather conditions. Nevertheless, about two weeks ago, I finally got started. This year, the first caterpillar belonged to a blue. To be more precise, it was a Common Blue (Polyommatus icarus).

The success felt good, and one of my season’s targets this year is to focus more on finding caterpillars (and eggs) of blues. Last year, my first caterpillar was a Small Copper (Lycaena phlaeas).

I hope this is a good start into a great caterpillar season.

Blue’n orange

There’s a particular moment after midsummer when various species of the Blues and Fritillaries hatch. During those days it feels like almost all butterflies around carry blue or orange shades. It’s also one of the most difficult times to properly identify sighted species. Please drop me a not in case I’ve misidentified any of the creatures listed below.
