After many days without rain in Tabasco, last night we finally had some rain, this morning me to try to catch drops of water in the trees and I found these drops in interesting ways caught by the silk of a spider (spider cloth)
Something on the silk of the spiders:
The spiders use the silk it is the elaboration of complex traps to capture their preys. Knitted by instinct, these cloths adopt varied and sometimes very specialized forms
The silk of the spiders is a fibrous protein segregated in form of fluid that, when extending, it forms a much more resistant polymer that the steel, and it multiplies its resistance to the break, grace to its elasticity. An only spider can produce several silk types. Although there are other spineless ones able to produce it, the spiders are those that make a more varied use of her. For example, they produce haulage threads that they help them to be guided and to be held in the event of fall. The small spiders, and especially the youths, knit a thread ‘parachute ' that allows them to be allowed to take for the wind, in occasions up to hundred of kilometers of distance. The males use the silk to transfer the sperm to the organ copulador, and the females make buds with her. The silk is also good to make nests and other cameras, as well as to have galleries. The good known use —y the most astonishing—of the silk on the part of many species is the elaboration of the traps for insects known as spider cloths. Once caught the prey in one of these cloths, the spider can wrap it with more silk.
The diverse cloth types that they knit the spiders represent a remarkable example of the evolution of the instinctive behavior. The spider doesn't have to learn how to knit her cloth, although the act of making it can be adapted to different circumstances. The simplest are irregular and the most complex cloths are entangled and they are guided to intercept the step of the flying insects. The elaboration of the cloth is a complex process that implies the creation and later elimination of hairsprings by way of scaffolding, and a combination of adherent and not adherent threads. In some cases, a group of spiders builds kind of a communal cloth, but in general the spiders are not social. Such spiders depend in great measure of the sense of the tact.

Original capture, Nina! If you don't look too closely it looks as though the water droplets are suspended in mid-air! Good DOF and composition. The only thing that I might try to "touch-up" is the bit of brightness on the right side of the leaf - IMHO it draws the eye away from the droplets.... other than that, lovely shot! And great note - thanks!

Very interesting view Ninfa. The droplets are very clear and I like the reflections - looks almost like small pearls or diamonds. Colours are very good too. You did a very good job here - not to forget collecting the informations in your note - thanks a lot.

Great droplets you found caught in the spider's web, Ninfa! They are beautifully glistening with the way the light falls on them, and I like how they are wrapped amidst the green leaf. Outstanding and informative notes, too. Very nice.
