[Astuces] Protection anti moustiques, comment se protéger
-
Une autre molécule reconnue comme efficace est le citriodiol (je n'en ai néanmoins pas trouvé en pharmacie) ; extrait d’huile essentielle d’eucalyptus, elle est reconnue comme aussi redoutable que le DEET, sans ses inconvénients (elle est toutefois déconseillée aux femmes enceintes et aux enfants de moins de 30 mois)... Je suis preneur de toute information sur un produit commercialisé utilisant cette substance !

AmphibiaWeb - Hyla arborea
-
In suitable habitats in the southern part of the range this is a common amphibian. For example, in the south of the former Soviet Union up to 20 specimens per 100 m of pond shore may be counted in spring. After reproduction, the population density is maximum in river valleys covered with broad-leafed trees.During the day, H. arborea usually sit on the stems and broad leaves of trees, bushes and large herbaceous vegetation. The frog is active primarily in the evening and at night, when it comes down to the ground from vegetation to forage and to rehydrate. During the autumn migration to hibernacula, H. arborea are active during the day. Hibernation occurs on land from September - December to February - early May, on land (in soil, burrows, heaps of stones and holes in trees). Reproduction occurs from April - May, but sometimes in March, June or even late July. As a rule, more males are found in breeding pools than females. Females enter pools after males and leave immediately after breeding. Clutch contains about 200-2000 eggs deposited in portions, usually having the form of small rounded clumps containing from 3 to 100 eggs. Metamorphosis occurs from June to September, depending on the geographic position of a locality. In some cases, the larvae overwinter and complete transformation the following summer. Young froglets in the first time remain on the shore climbing grass and small bushes. Hyla arborea prey mainly on insects. Its ability for long leaps makes it possible to forage on fast flying insects, which comprise a considerable proportion of its food. The frogs forage on land. During the breeding season, adults forage periodically on the shore and on high plant stems above the water surface.
