May 29, 2016: collected what might be a silken spider egg sac, covered with dirt or sand, on the stem of Grove Sandwort, Moehringia lateriflora.
(Thanks to several members of the Iowa Native Plant Society for the plant ID.)
a similar undetermined dirt or sand covered silk

June 23, 2016: 3 dead wasps, and what special wasps they are

checked the jar more carefully and found another silken sac on the back side of one of the leaves
