Spiderlet

"The most curious of all are the ground spiders like the Lycosae which drag the egg sac around attached to the posterior end of the abdomen, or in some cases held by the chelicerae. When these latter hatch the young spiderlets climb on to the mother and let her carry them about."

"Horticulturists know that a pampered spider-plant will not produce its offshoot stolon (its spiderlets); only when its soil is not rich and fertilizer is withheld (i.e., the spider-plant feels starved and threatened) will it start producing stolon in profusion."
