Dragonflies do imperfect metamorphosis. These insects put eggs in the water to become nymphs and then larvae. Adults will wing and get out of the water to fly freely. Larvae can be up to three years old, while adult dragonflies are only about 4 months.

Slender skimmers perch unmoving in bushes and dry twigs for a long time. They are able to capture almost all prey with a success rate of 95 percent, and even often eat butterflies and other types of dragonflies while still flying.

God is tools

God and spirit are controversial discussions in science and even mythology will have no place among naturalists and for Darwinians. Apparently this has been final that mythology is a delusional, mystical and superstitious concept that cannot be empirically proven in the world of science.

Most scientists and science activists have agreed that god is nonsense, delusional and cannot be accommodated in the theory of evolution. This opinion can be understood methodologically and I agree with the sentences. But so many behaviors are very real and occur in the field.


I am a fieldman who goes to the wild every day, along rice fields and forests to watch insects to plants, talk to people especially in villages, visit Hindu-Buddhist temples built in the 8th century, witnessing busyness in mosques, temples and churches.

I feel something is missing in the view of naturalists and Darwinians. There are short moments that are missed in analyzes in the timeline of human evolution. These little moment…
