Eristalis tenax

The family of Babblers is Syrphidae. An adult fly with a brownish breast and a yellow-black spotted belly is very similar to a bee. Noteworthy is the larva of the beekeeper, which is called "rat". The body of the larva is barrel-shaped, indistinctly segmented. The last three segments of the abdomen form a characteristic "tail" - a breathing tube. These segments are thin, and each subsequent one can be drawn into the previous one or, conversely, quickly move out of it. At the end of the breathing tube there are two spiracles, and inside there are two thick tracheae. The fully extended breathing tube of adult larvae reaches a length of 12-15cm. The larva descends deep into the reservoir, leaving the end of the breathing tube on the surface of the water. The larva pupates in the soil near the reservoir.
