The Narbonne Lycosa: The Burrow
see my Lycosæ, now this batch, now that, building, at the entrance to the burrow, a convex ceiling, which is difficult to distinguish from the surrounding soil. Can it be to protect themselves from the too-vivid light? This is doubtful; for, a few days later, though the power of the sun remain the same, the roof is broken open and the Spider reappears at her door, where she revels in the torrid heat of the dog-days.
Later, when October comes, if it be rainy weather, she retires once more under a roof, as though she were guarding herself against the damp. Let us not be too positive of anything, however: often, when it is raining hard, the Spider bursts her ceiling and leaves her house open to the skies.
Perhaps the lid is only put on for serious domestic events, notably for the laying. I do, in fact, perceive young Lycosæ who shut themselves in before they have attained the dignity of motherhood and who reappear, some time later, with the bag containing the eggs hung to their stern. The inference that they close the door with the object of securing greater quiet while spinning the maternal cocoon would not be in keeping
