Notes on Perithemis tenera in Michigan

Of the eleven species of this primarily neotropical genus, one widely ranging species - P. tenera - is found here in Michigan. Most records are from the southern LP, but one record is from Chippewa Co., UP (Map 1).

These small, stocky larvae are found in ponds and slow-moving or quiet sections of streams (Walker and Corbet 1975). Morphologically, they appear almost as corduliids, with a prominent, broad abdomen with middorsal spines on Ab9 and the distal margin of the palpal crenate. Larvae are probably univoltine, and emergence in Michigan probably occurs during June and early July. Little is known about this species' larval ecology or biology.
