Clouded buff, Diacrisia sannio. It worked; with a little patience, I was able to document the final phase. It was exciting to see how the larva developed a shiny, metallic head shortly before pupation.

Category: most beautiful insects on earth. Cuckoo wasps are one of my favorite insects. I love the play of colors and the metallic look. No pigments, just light refractions with surface textures in the nanometer range. These „colors“ never fade. Encased in amber, they last for several million years.

Hawk moths, or they big and beautiful caterpillars😍 Pappelschwärmer, poplar hawk-moth (Laothoe populi) Lindenschwärmer, lime hawk-moth (Mimas tiliae) Totenkopfschwärmer, death‘s head hawk-moth (Acherontia atropos)

One of my favorite insects: any kind of cuckoo wasp. These shiny, metallic flying gems always invite me to take a break and observe them, whether I’m out for a walk, in the middle of a conversation, or in a hurry. Simply fascinating.

Bee under UV-light (365nm) The bee doesn’t really fluoresce like some caterpillars and in reality (for the human eye), the eyes shine much more than the hair. There is probably a shift in the wavelengths inside the camera. But still an interesting perspective. Heading up for eggs and caterpillars. 🥰

Some larvae I observed in the garden. These are the larvae of Hymenoptera. The larvae usually live on plants and resemble butterfly caterpillars. There are about 800 species of sawflies in Central Europe. I think the larvae’s eyes, or rather their dark outlines, give them a rather cute face.

Cuckoo wasp, Chrysididae, abdomen. These colors are created by thin layers of chitin that refract the light. These interference colors do not fade as long as the layers remain intact. These colors can also be found in some insects that have been encased in amber for millions of years.

Death’s-head hawkmoth, Acherontia atropos. What was particularly exciting was the discovery of the forked hairs on the sides of the caterpillar (see second image). It also made it into our book, in a special chapter on death’s-head hawk moths.

Birds are particularly sensitive to this color. Red serves a warning function in nature. Red insects use it to signal that they are poisonous. Some are poisonous, others simply use the color.

Purple thorn, Selenia tetralunaria. With its wings open and spread upwards, it sits as if it’s about to take off. But that’s its resting position, invisible in a pile of leaves. Here I was able to practice my outdoor skills once again and take 14 individual images of the head.
