Since I especially like beetles with horns and since I realised they are distributed at least across two families, I've decided to set up a traditional project to get an idea of the number of species and variability of the horns.

23.2.24 In the vegetable drawer of the fridge I found a caterpillar. It must have come out of the cauliflower. I put it in a box with holes ( when I raised young swifts I had to buy a lot of crickets, which came in clear plastic boxes with holes. I kept them just in case...) and gave it a bit of cauliflower leaf.

25.2.24 It has attached itself to the lid of the box.

27.2.24 Now it has pupated.

I kept the box first in the storeroom, a room next to the kitchen which is open to the patio, so always cold. When we got a really cold spell at the beginning of March, I brought it into the kitchen. It is not heated anyway and cooler than outside when the sun is shining, but not as cold at night. I checked on my inhabitant daily, but didn't see any changes.

17.3.24 The pupa had changed colour and looked darker, I feared it had died.

19.3.24 What a surprise! The butterfly has hatched! It kept sitting on the pupa and didn't move.
I opened the box and took some photos.

I put the lid with the butterfly into the patio, where eventually the sun would shine in. Then I had breakfast. When I checked again, it was gone.
So, I didn't observe any of the stages, neither the making of the pupa nor the hatching or the flying off and anyway it is one of the most common species, sometimes even considered a pest, but I am still happy!
