Two spiders of different species and Families, in a risky position for each of the two, given that the spiders can prey on each other. One, sticking out from a hole at the base of a recess in the wall, is an Agelenidae; the other one, on the wall above the other, is a Steatoda grossa, Theridiidae.
In my basement, a little drama unfolded: #Agelenidae vs #Theridiidae! Steatoda grossa (Theridiidae, on the wall) ran very quickly too close to the Agelenidae (on the ground), which didn't like the invasion and took off running after it.

(Pero me costรณ un montรณn sacarles fotos, son diminutas)

En este macho son muy evidentes los bulbos copuladores en los extremos de los pedipalpos, que permiten diferenciar fรกcilmente los machos de las araรฑas en todas las especies (que yo sepa)

Este tipo de parasitismo que se aprovecha de las presas del otro se llama cleptoparasitismo.

Estรก ahรญ porque parasita las telas de araรฑas mรกs grandes, alimentรกndose de las presas que cazan, y a veces incluso de sus crรญas.

Se trata de una araรฑa diminuta, si no la buscas expresamente lo mรกs probable es que no te fijes en ella. Su nombre cientรญfico es Argyrodes argyrodes, y el comรบn, araรฑa gota de rocรญo.

En las telas de las Argiopes y otras especies, como Nuctenea umbrรกtica o Cyrtophora citricola (es donde las he visto yo), si ponรฉis atenciรณn podrรฉis encontrar una araรฑa diminuta plateada.
