This is one of the biggest insect groups. Both, anterior and rear, wings are transparent and membranous. The anterior and rear wings are coupled together and operate as a single whole. Most famous representatives are: bees, wasps, bumblebees, ants, etc.

Photos 10-13 Ц wild bees.
Photo 14 Ц winged pubertal ants. The winged forms of ant appear only in autumn, survived insects will give an origin for new ant colonies.>
Photos 20 and 21 Ц small wasp nest.
Photos 15, 19, 22-28, 30, 31, 36 Ц parasite wasps. It is more precisely they are parasitoids, because these wasps lay their ova on larva-prey which are alive or paralyzed. The wasp larva carefully eats prey without killing. Photo 31 Ц pupa remains (caterpillar skin is already absent). Photo 19 - dauber (Ammophilla sabulosa), it paralyzes and drags caterpillar to the hole dug in advance where the wasp lays ovum on caterpillar. Unfortunately, to shoot wasp in moment of dragging the caterpillar on the ground between legs was impossible. When somebody came to wasp, it threw prey and flew away. Small wasp-parasitoids lay more than one egg on live caterpillars. It is very rare case for observing when a wasp flies closely to a caterpillar and touched it with end of abdomen, i.e., by ovipositor, after that the caterpillar fell on the ground or wriggled, but it was late, the ovum was attached to skin. Certainly, to shoot at this moment is impossible.
