Mysterious Egg Sac in Algonquin Provincial Park. Many Insects and Spiders construct distinctive Egg Sacs with Silk, saliva, or other materials produced by their bodies or found in their environments. This picture is of an Egg Sac found in Algonquin Provincial Park earlier this month. When I consulted the definitive guide to such things (Tracks and Sign of Insects and Other Invertebrates, by Charley Eiseman and Noah Charney), I found this type of Egg Sac described as commonly encountered but still mysterious. The authors said that they were fairly sure this type of Egg Sac was constructed by Tetragnathid Spiders (Long-Jawed Orbweavers). A later blogpost by Charley Eiseman on his amazing blog Bugtracks confirmed that at least some of these types of Egg Sacs produce Tetragnathid Spiders (the ones in the post were of the genus Tetragnatha). . It's a fascinating world out there, especially if you take the time to pay attention to and appreciate the little things. The authors of Tracks and Sign of Insects and Other Invertebrates have certainly done so, and I would highly recommend their book. . . . . . . . #nature #ontario #algonquinprovincialpark #algonquinpark #tetragnathidae #tetragnatha #spidereggsac #tracksandsign #bugtracks #ontarioprovincialparks #appreciatethelittlethings #fascinatingspiders #spiders_of_the_world #spider #eggsac #spidereggs #macro #macrolife (at Algonquin Provincial Park) https://www.instagram.com/p/CEbWx8Ogo3y/?igshid=1oe8ec2nem268
