Baetisca (Armored Mayflies) Mayfly Nymph
View 4 PicturesI've only got blurry pictures of this small Baetisca nymph, because it was zooming around the container in a frenzy. Several characteristics, if taken literally, suggest that it may be Baetisca lacustris. However, it's very small and it's the only candidate lacustris I collected among several laurentina specimens, so it's possible this is just an underdeveloped 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.) laurentina.
