Though it may be conceded that themegalopterous larvae are relatively generalized modern forms, theyare nevertheless superficially modified for aquatic life, and life in thewater does not account for their more fundamental characters, whichare those of endopterygote larvae in general. Most larvae can be reared without difficulty, but need cold water and some flow. It helps them when moving in the current, or even prevents from being washed downstream. The larvae target good emergence sites such as bridge abutments, wood debris, fallen trees, exposed tree roots, aquatic plants, and most often, rocks.

Stoneflies spend most of their lives as larvae in the water, crawling along the bottom of streams and rivers, and clinging to the underside of rocks and woody debris. If conditions become stagnant, stonefly lar-vae will begin doing “push-ups.” This behavior helps They love clean environments and their presence indicates very high water quality. The affinities of the third suborder, Spicipalpia, are unclear; the larvae are free-living with no cases, instead creating net-like traps from silk. This is a season of joy for fish living in stonefly laden streams. Like most holometabolous larvae, they have well developed mandibulate mouthparts and the thoracic legs are well developed, but abdominal prolegs are absent except for a pair of anal prolegs on the last abdominal segment, each proleg bearing a strong "anal claw." ���n��p�6]���~�����o�����~?~}�����v|�8�{��0�+1������3��nk��1;N��t����ƍǻż�Nj_�Y��^ÞP[��i�w̕�˲�qУ�‚Pa���H���9\3��{���=�'�3�p�V�:"���&}C]s��A���|{7�Gt{�������뻩�L ��EX�J����a�&����� i�ן��%W �҇u�f$�C�;�e�;�7��kZ= Ƶ���$��04�+�k90 �8콌��Q���� �甌�D��4�،+�E�9.�o�|�k�@Jy~a w�x�MjGYs��fk��L=��ז�d������ؔ���"5������ed� �r��Dž}���* ׎��۔��f Stoneflies are found worldwide, except Antarctica. nata (Plecoptera: Perlodidae) living in high altitude streams in western Colorado and to measure the e ects of size at metamorphosis on (1) male reproductive suc- Stonefly larvae are common inhabitants along the bottoms of rivers and streams. 6 47 They demonstrate an intolerance of pollution and narrow tolerances of water temperature and related parameters.
