On Thursday with the warm temps and bright sun I walked up to a nearby rock outcrop that I know as one of the only places to find lowbush blueberries. On my way up I stopped at a section of Cobbs Creek to see what I could observe about fish – there were many but they were all under water. On the elevated rock plateau, the blueberries were in full flower and quite busy with native pollinators and one honeybee. I watched them for a few minutes, then I spent about ninety minutes sitting on a rock ledge looking at wildflowers, spleenworts and watching Megachilid bees entering their ground nests. The surprise for the day came from a series of vertical silk tube structures that were striking but unfamiliar to me. After some research I found they are the artifact of a small reclusive spider closely related to tarantulas that is known only from Delaware Co., PA and was not named as a species until 1972. A new effort to map the distribution of the spider uses a phone app called Epicollect5 to report searches, findings and locations. I documented the webs (over 24 of them) and submitted my data to the mapping effort. My field notes from the day (still incomplete) are below. 
Pussytoes, Antennaria parlinii [ASTERACEAE] alongside the blueberries
Vertical silk tube webs of the Pennsylvania purseweb spider, Atypus snetsingeri, the only spider in the genus Atypus in the USA.
