Ten nests of Sceliphron fistularium were obtained in two sites: Panama Oeste province, shores of Gatun Lake, Jungle Land Panama, and the province of Panama in the building of the School of Biology, University of Panama, Central Campus. The complete nests consisted of 3 to 14 cells, making a total of approximately 79 cells among the 10 nests. The nests were tubular in shape with the upper end oval and the basal end with a slight decrease in acute form, arranged side by side along a horizontal axis, and were found attached to different artifacts: a telephone wire (Campus Central University of Panama, n = 2); in three plastic chairs and two in wooden ceiling beams, installations of a floating boat (Gatun Lake, Jungle Land Panama, chairs n = 5 and wood n = 3). The number of cells per nest ranged from 3 to 14, their length ranged from 32.5 to 38.6 mm and their diameter from 15.3 (anterior) to...
