<p><span class="done">Cordulegastridae (emeralds)</span> Members of this family tend to prefer small, cool waters such as forested streams and bogs, but have also been found in slow, shallow waters and in larger, more open waters. 
They may either sprawl or climb; sprawlers tend to move about almost constantly while climbers use all types of vegetation and debris. They require one or two years until emergence, which typically occurs in spring and summer.</p>
