TL;DR: Ballooning, a form of dispersal rarely seen in mygalomorph spiders, was observed one early spring day in about 30 Sphodros spiderlings as discussed by the authors, which became airborne by dropping and hanging from a dragline which then gradually lifted and lengthened in the breeze, broke at its attachment point and served as the ballooning thread.
Abstract: Ballooning, a form of dispersal rarely seen in mygalomorph spiders, was observed one early spring day in about 30 Sphodros spiderlings. After ascending a stump, each spiderling became airborne by dropping and hanging from a dragline which then gradually lifted and lengthened in the breeze, broke at its attachment point, and served as the ballooning thread. Although less effective than the aerial dispersal mechanisms of many araneomorph spiders, this technique can nevertheless produce higher and longer flights than Bristowe and others have suspected.
TL;DR: There are three purse-web spider species in Kansas, all in the genus Sphodros, which are known only from the eastern edge of the state, while the range of S. fitchi Gertsch and Platnick extends into western Kansas which is the westernmost distribution record for the family in the New World.
