The spider, name unknown, is large and builds a correspondingly large web, characterized by an extra-thick zig-zag ladderlike vertical feature in or near the center. This morning a gulf fritillary had been trammeled in the web, which had been constructed in the midst of the passionvine. The butterfly was already dead when observed. This evening the butterfly was gone and the spider was there. We have so many fritillaries and not quite so many pipevine swallowtails right now.
