Adults of these dragonflies are powerful fliersand migrate considerable distances, and are world-wide indistribution. Two species have been recorded in Michigan. Like othermigratory dragonfly species, larvae can develop in short periods oftime and can thrive in temporory bodies of water.
T. lacerata isfound in open marshy lagoons and bays, probably does not overwinterin the larval stage in the morthernmost localities where adults havebeen recorded. Nymphs taken in s. Utah from a spring pond containingwatercress and other aquatic plants with trees and bushes surroundingthe pond; but elsewhere nymphs may occupy ponds without surroundingtrees (Musser1962). T.carolina is found in clear waters ofponds and small lakes, especially those with rooted, submergedvegetation, and occasionally in quiet streams.
