Baetisca (Armored Mayflies) Mayfly Nymph Pictures

 This very small, early instar (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.) specimen has some interesting markings, but it's too underdeveloped to identify.

This mayfly was collected from unknown on January 14th, 2004 and added to Troutnut.com on January 25th, 2006.
