"Spiderlings alone may seem unthreatening, but their presence should be a warning for travelers. For wherever there are spiderlings, there will be matriarchs, and the fully grown arachnids are extremely protective of their young. The spiderlings themselves possess strong appetites, allowing them to do considerable harm to a cornered adventurer"

Spiderlings are encountered in Wortham, Ashwold Cemetery, the Dark Wood, Shassar Sea, and Mount Zavain.

Diablo III

Spiderlings are a lesser, but more numerous type of spider. Spiderlings swarm around, trying to take heroes down by sheer numbers. They often spawn from eggs, or just wait in the shadows, pouring through like an endless tide. Cydaea also summons them in large numbers.

Overall, Spiderlings are not dangerous, easily dealt with by using any area attacks. However, they can (and often will) block path, making hero unable to deal with more dangerous ranged attackers. They also award less experience and loot than normal monsters.
