Two Aedes stimulans and Aedes provocans mosquito larvae, hang from the surface of the water breathing through their air tubes.  These species of mosquitoes are very common in the woodlands of North America.  They develop in vernal pools, emerge in large numbers and their fierce biting habits make them a large human pest.

Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

Zerynthia polyxena, the southern festoon, is a butterfly belonging to the butterfly family Papilionidae.\nDescription:\nThe southern festoon can reach a wingspan of 46–52 mm. The females have slightly longer wings, usually lighter colored than males. The basic color of the wings is yellow, with a complicated pattern of several black bands and spots. \nOn the edges of the hindwings they have a black sinuous line with a series of blue and red warning spots to deter potential predators (aposematism). The body is dark brown and bears red patches on the sides of the abdomen. \nThis species is rather similar to, and can be confused only with, the Spanish festoon (Z. rumina). The differences are in the presence of blue on the hind wings of Z. polyxena and the relatively lower amount of red on its forewings compared with Z. rumina. The ranges of these two species overlap only in southeast France. \nThe caterpillars of Z. polyxena are up to 35 millimeters long. They are initially black, then they are yellowish with six rows of fleshy orange and black spikes all over the body. \nHabitat:\nThese rare butterflies can be found in warm, sunny and open places such as grassy herb-rich meadows, vineyards, river banks, wetlands, cultivated areas, brushy places, wasteland, rocky cliffs and karst terrains, at an elevation of from 0 to 1,700 meters above sea level but usually below 900 meters.\nDistribution:\nZ. polyxena is widespread in the middle and southern Europe (southeastern France, Italy, Slovakia and Greece) covering all the Balkans and reaching the south of Kazakhstan and the Urals. Although they are widespread they occur only locally (source Wikipedia).\n\nThis Picture is made during a Vacation in Bulgaria in May 2018.
