Hi,

This wolf spider is the only Lycosidae on St Barth, its environment is incredibly small. :rolleyes:
She lives only on two small islands in the middle of a salt marsh. I looked for him everywhere else around the salt marsh and everywhere on the island and i never found her.

For spiders, I always write in the feminine to speak about the species.;)

A little ground dry in the middle of the salt water.;)

Can be that this photo shows better or it finds the environment.

oh... well if that island is there for a long time maybe they form their own species... or die from too much inbreeding {D

Juvenile wolf spiders are good ballooners, that's how such spots are colonized! The little island is not really isolated from the surrounding land mass.

Wind dispersal is a very important mode of transportation for small spiders and and a very succesfull strategy for conquering new habitats.
E.g. spiders are often among the first animals to establish on the barren land after a vulcanical eruption, as generalist predators they can feed on the variety of winged insect brought by the wind.

Still, the species composition and food web on this island must be be very interresting!
Thanks for sharing these photos!

Cheers
