My wish list for Aosta included three things: the Iolas Blue, the caterpillar of the Piedmont anomalous Blue and the caterpillar of the Apollo. One and a half week ago I visited the hotspot of the Piedmont anomalous Blue and very soon I noticed three ants on Sainfoin and when I looked closer I saw a beautiful caterpillar. Unfortunately I did not have my camera with me so I had to get it first...when I returned one ant was still protecting the caterpillar. As no image of the caterpillar of this species was available on internet, nor in books, I contacted one of the researchers of this species and she confirmed that this was the caterpillar of the Piedmont anomalous Blue. I was very happy that I found the caterpillar of this species and with the confirmation I also knew that I photographed this caterpillar before in 2021.

Since more than a week we have spring temperatures and on the 15th I noticed the first butterflies of this year (three Brimstones). Normally I visit them early March but with this sunny weather I was curious if the caterpillars of the Glanville Fritillary would be already active. Yes they are! My old workhorse joined me as I did not read the manual of the Sony yet :-(.
Due to this fabulous summer, I found some caterpillars of the Swallowtail. First in July on a carrot field which was gathered the day after and second in August on fennel. I received some fresh fennel to feed them and when they were all almost grown and pupated I discovered a tiny little caterpillar which was just born....so the complete story continued. Last Monday evening I run out of food for the last caterpillar as my fennel is empty. I drove to a carrot field and found immediately a tiny little caterpillar. Although it was getting dark I searched on a place with high weed between the carrots (a sign that this piece of land was not treated with poison) and found 11 caterpillars: As these caterpillars are very hungry and as I wanted to search for more caterpillars I drove to the carrot field this morning. Big machines were busy and the wilder part with weed was already completely gone. How many swallowtails we would have in the Netherlands when some of the carrot field would not be gathered?
Exactly one week ago it was still winter with freezing temperatures and fresh snow. Last Sunday the snow melted and in the afternoon spring arrived. I've rarely experienced such a big difference! After some warmer days nature has awakened and I was glad that some caterpillar nests of the Glanville Fritillary survived winter. Unfortunately their enemies survived the winter too as around almost each nest I noticed a parasitoid wasp. Some of them were already busy infecting a caterpillar en some of them were sitting in the grass around the nest. I guess that it is no coincidende from mother nature that the wasps (I assume pteromalus puparum) have the same colours as the caterpillars...black with red eyes.
After an absence of almost three weeks, I inspected my vegetable garden and found out that the cabbage area is a battlefield. In all kind of sizes I found caterpillars of the Large White and one caterpillar of the Small White. Eating any cabbage I can forget like every year.....I love this little creatures so the cabbage is for them. I must be content with some red tomatoes!
Nature it's on her best at the moment! Next to birds, deers also butterflies giving 'birth' to the next generation. Wherever I look, I find caterpillars, their enemies and other little creatures! Wanda (my shepard) hates them....actually not them but me walking slowly through the forest and searching for them. In almost every Alder Buckthorn (Rhamnus frangula) caterpillars are living: I also found some caterpillars of the Red Admiral and Comma Butterfly in my garden. Unfortunately all the caterpillars of Red Admiral which I found in my garden were parasited. When I unfold the nettle leaf I noticed an opening at one cocoon and a few minutes later I witnessed the emergence of a parasitoid wasp. The newborn wasp flew to a higher nettle leaf and allowed me one image before she flew away to search for new victims:
At the moment it's caterpillar time outside! In the last two weeks during my walks with Wanda I found at least thousand caterpillars in two area's. Leading is the Map Butterfly (after 25 caterpillar nests I stopped counting them) followed by the Red Admiral (on almost every nettle plant I found a caterpillar). In my own garden I found at least 25 caterpillars of the Red Admiral and two caterpillar nests of the Map Butterfly. More by surprise I found one caterpillar of the Comma Butterfly and again I had the hope to finish my 'battle' which started in 1999 (see/read my chapter metamorphosises). Last year I had two caterpillars of this species but one was parasitized and the other emerged during the night. In 2014 I missed the emergence process as the butterfly was 'born' during the night. So I was very happy with this new chance and very soon after I found the caterpillar he started to search for a good place to transform into a chrysalis. Unfortunately my Comma Battle will continue as this beautiful caterpillar was parasitized and an ugly larva hatched from my one and only comma chrysalis!
A few days before my holiday started (almost three weeks ago) I noticed three female Holly Blue butterflies on my two big Purple Loosestrife (Lythrum salicaria) plants. In the evening I discovered one fresh egg and marked this place. When I returned last weekend, I found a caterpillar near the marked place and after the inspection of the complete plants I found a second caterpillar and four other empty eggs. Two days later I wanted to photograph the caterpillars but although the stem was marked, it took a long time before I found them back.....they had switched the stem and due to their 'simular to the flower' colour they were almost invisible. One caterpillar, the left one was eating between the pink flowers was coloured more red and the other one, the right one, was eating the green flowerbuds on the top of the stem and was more greenish. When the first caterpillar was ready to search for a nice place to pupate, his colour had changed again and between the leaves he was again not visible.
Although I know that nature is that clever, I'm impressed and fascinated again! A lot of fennel was growing in the meadows of the accomodation in France and with a lot I mean hundreds of plants. So it was no surprise that the Swallowtail was a regular visitor and that the females were laying eggs. But when I liked to photograph an egg a few days later the egg was gone; instead I found some fat ants. I watched this proces, called nature, some days and decided to intervene. I took some fennel with yellow eggs and put it outside in the window-sill of the accomodation. Afer a few day, more by accident, I noticed a little dark spot and after I found my glasses I noticed that the dark spot was a hatching egg. With my MP-E 65 mm I could follow the birth but there was too much wind outside to photograph this proces. After the birth this tiny little caterpillar started to eat the egg shell and inbetween he took a break....time for me to make some photos. Ever tried to photograph something with a longer shuttertime on a fennel leaf? The leaves of fennel are always in motion. After some photos I relooked them in the screen of my camera and could see that the tiny caterpillar started in the choosen (higher) position and after some shots he was that low that I needed to change again the compositon. Fortunately I had enough time that day to repeat that proces again and again and again. I'm happy that I can add this young caterpillar (5:1 magnification) to my personal Swallowtail image collecion.
