Hawk-moth saldo 2016

In summer 2016 my goal was to spot some caterpillars of Hawk-moth species that I haven’t come across recently. Here’s a wrap-up of all species I managed to find, including the the hummingbird hawk-moth (Macroglossum stellatarum) from which I received caterpillars from a friend.

There’s a lot of challenge left for next year. Nevertheless, it was nice to finally find caterpillars of the Privet Hawk-moth (Sphinx ligustri). Another nice surprise was to spot a caterpillar of the Eyed Hawk-moth (Smerinthus ocellatus). All in all, it has been 7 Hawk-moth species in summer 2016. And bottom line, it’s always a great moment when coming across caterpillars of hawk-moth.

Becoming a butterfly

Most people take butterflies for granted. They may also not care about the long journey a butterfly has past before ever taking off with their wings. Nevertheless, in case of the Purple Hairstreak (Neozephyrus quercus) it takes almost a year before the butterfly has completed the metamorphosis. The adult butterfly will live a couple weeks, copulate, lay eggs and die.

Following the metamorphosis close by means a lot of work. Most likely, the butterflies need to be raised with a lot of care. Dealing with the Purple Hairstreak, the eggs need to be searched and found in autumn. After that, these eggs need to be stored for hibernation. This phase may take up to 8 months. In spring, the tiny caterpillars will hatch. In summer, finally, the butterflies will hatch and show their beauty.

Early summer hatchings

Time passes. Before one can realize that summer has started it is usually already over. Late spring and early summer was particularly busy this year since we had to arrange our move to our new home. At the same time also most of the chrysalises that overwintered, either in our fridge or on the balcony, hatched.

I rarely managed to keep the camera close by, most commonly I only saw some butterfly that hatched before taking off. However, I did get a couple shots from some of the species. It was nice to see that the Lime Hawk-moth (Mimas tiliae), which our daughter found as slightly injured caterpillar, managed to complete the metamorphosis.

Like the year before, I also had a couple Poplar Hawk-moths (Laothoe populi) overwintering. It was great seeing the difference in both sizes and coloring across individuals. The Small Emperor Moths (Saturnia pavonia), which I received as eggs from a friend, were true beauties. I remember one afternoon when I returned from work, there was quite some buzzing on the balcony. Due to a couple females that hatched the same time they managed to attract multiple males that were flying around. I’ll get back with some more photos from this species later on.

At the playground

Playing at the playground with the kids may bring a surprise every once in a while. I spent a lot of time during late summer finding caterpillars of the Privet Hawk-moth (Spinx ligustri), but the only ones I found were right at the playground. Two playgrounds, to be precise.

After the first caterpillar already had parasites I was lucky enough to spot another one. The second was entirely healthy. It was also younger compared to the adult caterpillar found two weeks earlier. While I was watching after our three kids my wife was kind enough to bring my camera from home, so I managed to get a couple shots from the beautiful Privet Hawk-moth caterpillar right in its habitat.

Autumn at the allotment gardens

In October it starts getting difficult to find caterpillars in the wild. This time of the year I usually take a lazier approach and visit the allotment gardens located nearby. There’s still plenty of food plants attracting butterflies to lay eggs on, and particularly the Large White (Pieris brassicae) and the Small White (Pieris rapae) are species that can be found.

Both species commonly migrate to Finland from South in late summer. In 2015 I found masses of Large White caterpillars. Early October this year, it was primarily Small White caterpillars. These are more difficult to spot, but due to the feeding traces it’s easy to know when they’re around.

While there was caterpillars on different instars also eggs could still be found. Here’s some photos. The yellow line on the back is a clear indication for determining the species. The Green-veined White (Pieris napi), the most common of the Whites in the region, has in general a caterpillar that looks pretty similar.

Elephant in disguise

Commonly, caterpillars of the Elephant Hawk-moth (Deilephila elpenor) are spotted when they’re on their way to find a suitable place to pupate and hibernate. That is at their final instar, when the caterpillars are large and brown. Perhaps some 5% of the full-sized caterpillars remain the green color, which also makes it more difficult to spot them.

Younger caterpillars do a much better job hiding themselves. Since the species is common, it’s worth though taking a closer look at willowherbs, the food plant of the caterpillar. If the time is right the chances are good to find some. Below is a series of photos from summer 2016. I could spot a couple mid-sized caterpillars.

 

Orange Tips everywhere

Early June this year I tried my last attempts in finding caterpillars of the Lesser Purple Emperor (Apatura ilia). While I had no luck with this species there was another caterpillar that seemed to appear everywhere. Regardless what the location was, there were always caterpillas of the Orange Tip (Anthocharis cardamines).

Of course, I must admit that I did like to keep an eye on the suitable food plant. In the previous year the Orange Tip was one of my season’s targets to raise. I guess it’s all about learning how to find caterpillars (or eggs). Once learned, they’ll appear everywhere. I did not take any caterpillars for raising this summer, but I took the chance to get some photos from the wild.
