Con un cuerpo de solo 5 a 6 mil\u00edmetros, este peque\u00f1o ar\u00e1cnido luce un intrincado patr\u00f3n de tonos marrones, negros y blancos en el abdomen que se oscurece con el paso del tiempo. En lugar de tejer la t\u00edpica red circular, esta especie construye una l\u00e1mina horizontal de seda coronada por un enredo de hilos &#8220;trampa&#8221; superiores. Cuando un insecto choca contra los hilos superiores, cae sobre la s\u00e1bana, donde la ara\u00f1a lo ataca r\u00e1pidamente desde abajo a trav\u00e9s de la red. En las ma\u00f1anas de oto\u00f1o cubiertas de roc\u00edo, cientos de estas redes ocultas destacan en la hierba como mantas escarchadas. Tras el apareamiento, los machos suelen permanecer en la misma red para proteger a la hembra y compartir presas antes de la puesta de huevos. \u00a1Me encontr\u00e9 con esta fascinante ara\u00f1a en su sofisticada red entre la vegetaci\u00f3n del bosque cerca de Barkarby, Suecia!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Colgada completamente boca abajo bajo una delicada hamaca de
