🇬🇧Square-headed wasp, Lestica subterranea. Shown here is one of three ocelli. These are located on the head between the compound eyes. These allow many flying insects to detect differences in brightness and are thus likely used for horizon detection. 🇩🇪Schmetterlingsjagende

🇬🇧Rose chafer, Cetonia aurata. Close, closer... sometimes even the smallest details are fascinating. Here, the transition from the thorax to the scutellum at a scale of 50:1. 🇩🇪Goldglänzender Rosenkäfer, Cetonia aurata. Nah, näher… manchmal faszinieren schon die kleinsten

🇬🇧Cicindela hybrida, tiger beetle. One reason to take a closer look is the colors. Due to the small distance between the colors in such a small space, we humans can often only perceive the mixed colors. 🇩🇪Cicindela hybrida, Dünen-Sandlaufkäfer. Ein Grund genauer hinzuschauen

Death’s-head hawkmoth, Acherontia atropos. In the last caterpillar instar, L5, it only eats and sleeps (okay, in the other instars too, but now especially a lot). During one of the long power naps, I was able to create a stack of 97 individual images of the legs. What was

Rhynchites caeruleus. These small, shiny beetles are currently easy to observe. They initially appear black to our eyes, but upon closer inspection, they remind me of liquid metal.

Cuckoo wasp, Chrysididae. Here you can see the abdomen. These colors are not created by pigments, but 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

Jewel beetle, Anthaxia nitidula. Once you get a feel for the size of these beetles, they’re hard to miss. It took me almost 40 years to do it 😉 You can see the female on the top and the mal below.

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
