Cloeon dipterum is unusual among mayflies in being ovoviviparous, and is the only ovoviviparous mayfly species known in Europe. Females lay eggs 10–14 days after mating, and the eggs hatch as soon as they hit the water. The larvae can survive for months in anoxic conditions, an adaptation which is necessary to survive the winter in ponds which freeze over and therefore contain little dissolved oxygen. In captivity, adult females have been kept alive for up to three weeks.

20-4-2021 MARXUQUERA, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)
The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.
Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.
The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.
