对威斯康星州北部地区的鳞茎兰花、结节斑潜蝇和草鱼的繁殖生物学进行了研究。这三个种具有一些暗示趋同的花卉特征，但由于隔离机制，它们仍然是不同的。花的大小、粉红色的花被、有黄白色刷子的嘴唇以及唇刷对紫外线的强烈吸收是收敛的主要原因。物种之间的隔离机制包括在昆虫上放置花粉，部分季节性隔离，以及染色体的大小和数量。传粉者是不同种类的蜜蜂。
The reproductive biology of Arethusa bulbosa, Calopogon tuberosus, and Pogonia ophioglossoides was studied in northern Wisconsin. The three species possess a number of floral characters suggesting convergence, yet they remain distinct as a result of isolating mechanisms. Convergence is suggested mainly by the size of the flowers, pink-magenta perianth, lips with yellow-white brushes, and strong absorption of ultraviolet light by the lip brushes. Some of the isolating mechanisms between the species are placement of pollen on the insects, partial seasonal isolation, and chromosomal size and number. The pollinators are various species of bees.
