Hello. Help me determine what kind of insect is this?

Please tell me who it is. Moscow region, 04.09.2018. Does the imago of some beetle appear ? I didn't think they had so many layers.

The imago has already appeared. This is the pupal exuvium protruding from the last-stage larval exuvium. Ladybug from podsem. Chilocorinae, in some species, after the last molt, the pupa remains in the larval skin that has burst along the middle. In the Moscow region, this is exactly the case with Chilocorus and Exochomus quadripustulatus, maybe some other species. In my opinion, Chilocorus in Exochomus quadripustulatus outgrowths in larvae are not so large.

Whose caviar is this on the willow leaves growing along the ditches?
As they mature, maggot-like larvae are visible inside. The caviar gradually liquefies and they probably fall to the wet ground.
September 2, Pskov region

Dipteran tricks, I think. For example, this method of egg laying is described for representatives of the Anisopodidae family. But whether it is or not I can't tell you.

The masonry is more than 1 cm in diameter. These should be very large flies.

This is the masonry of some caddis fly (I'm surprised myself). Never wondered where they put their eggs
