Behavior - including newest, unexpected discoveries

Last 30 years brought significant and impressing progress in knowledge of behavior of Salticidae, due first of all to reesearch
of Robert R. Jackson and his numerous collaborators. That includes recognition "dances" and such surprising features as 
learning and developing new attack strategies, feeding on flower nectar (found for 90 species!), intermediate feeding on human 
and other mammals' blood (by preying on blood engorged mosquitoes in Africa), and building of communal "cities" by several
 species in Uganda. Prey specialisation involves preying on other spiders (including Salticidae, as well as their eggs). 21 species
were observed preying on ant (Clark et al, 2000) - none of them belonging to so called ant-like genera (that confirm once more that
ant-likenes is camouflaging specialisation only against other predators avoiding ants).  The reader is directed to original papers, 
listed under Jackson in the list of publications. Interesting observation of two species specialized in preying on termites in Africa
 gives Wesolowska and Cumming 1999, 2002. Earlier, hoisting of empty snail's shell on thread attached to grass, and using it as
 both retreat and suspended jumping platform, for atacking  insects flying by, was observed in Pellenes nigrociliatus by Mikulska, 
With growing knowledge of taxonomy, distribution and ecology of Salticidae it is advisable for Arachnologists to concentrate
 gradually more on behavior and photographing.
