Half-success with Sphinx ligustri

Since about two weeks I’ve had a special priority: To find caterpillars of the Privet hawk-moth (Sphinx ligustri). It’s the largest caterpillar that can be found in Finland and it almost looks like a gigantic candy.

The search has been exhausting and with my e-bike I’ve been riding several hundred kilometers, keeping a close eye on growth that the caterpillar accepts as food plant. While I was able to locate several other species of hawk-moths there was absolutely no trace of Sphinx ligustri.

Today, on the 5th birthday of our daughter we went for another visit to one of the children’s playgrounds nearby. I couldn’t resist checking some of the perennial herbaceous flowering plants decorating the playground. There it was, less than 500 meters from our home, an almost full grown caterpillar was feasting.

The caterpillars of the Privet hawk-moth are amazing. This is one of the species highly suitable for raising with kids. Unfortunately, the species also suffers great losses to parasites. The caterpillar found today was carrying over a dozen eggs of parasites on its skin. The truth is this specimen will never become a moth. Something else will hatch from the chrysalis. I’ll call this finding half-success.

Nevertheless, here’s some photos of the caterpillar. I’m sure we’ll find more over the next couple weeks. This one might be a bit early anyway.
