The little aeronaut as soon as it arrived on board was very active, running about, sometimes letting itself fall, and then reascending the same thread; sometimes employing itself in making a small and very irregular mesh in the corners between the ropes.

It could run with facility on the surface of water.

When disturbed it lifted up its front legs, in the attitude of attention.

On its first arrival it appeared very thirsty, and with exserted maxillae drank eagerly of drops of water; this same circumstance has been observed by Strack: may it not be in consequence of the little insect having passed through a dry and rarefied atmosphere?
Its stock of web seemed inexhaustible.

While watching some that were suspended by a single thread, I several times observed that the slightest breath of air bore them away out of sight, in a horizontal line.
