Comment: MEMI - approximately 2mm sized spiderling on my pants leg on the Moody Boundary; John & Jane Balaban think that this spider is a Mangora placida. That is what I had thought too. But they were not definitive. And, I have had another comment that it might be a Neoscona arabesca. So, if anyone has an opinion, please let me know. Laura P. from Bugguide agrees with Mangora placida. Alyssa Fuller says Mangora maculata.
