Jumper spiderlings

Yesterday Feb 19, could return to the place and register the birth of the first jumper spiderlings

Newborn jumper spider above the silk protection constructed by the mother, the eyes look not completely formed, possibly they born blind, esp the frontal one were very hard to focus, possibly they were below the skin, interesting to compare with the well developed mother eyes and see what they will turn in future. Photo with Canon 7D and Canon MP-e 65mm macro photo @ 5x magnification 



Profile of a newborn jumper spider (salticidae) spider I opened a small hole in the silk and this individual is finding his way out of it. The green abdomen fits the green eggs, it's like the face emerge from the eggs but I do not registered this to be sure. 


Detail of a single spiderling above the protective silk and with the mother feet as scale. Photo with canon 7D and Canon MP-E 65mm macro photo lens @ 5x plus a crop 



The jumper spider mother above the newborn salticidae babies, is possible to note some eggs still closed without spider in them and some with recently born spiderlings.  


Unfortunately after 4 days of rain the thing not ended well for the spiderlings, I think the rain trapped them in the web and they died, wonder how many times the weather interfered with the small things life.
