Northern Pygmy Clubtail Lanthus parvulus (Selys, 1854)S2 (State rare)  
Kingdom Animalia   >   Phylum Arthropoda   >   Class Insecta   >   Order Odonata   >   Family Gomphidae   >   Genus Lanthus   

Status:

The diminutive Northern Pygmy Clubtail (Lanthus parvulus) is scarcely larger than Eastern Least Clubtail, and like its congener, Southern Pygmy Clubtail (L. vernalis), it strongly prefers tiny vegetated streams and seeps to the larger waters most gomphids frequent. This northern species occurs only at higher elevations in Maryland, in Garrett and Allegany Counties (Richard Orr's The Dragonflies and Damselflies of Maryland and the District of Columbia). There is also evidently a museum specimen record from Montgomery Co. from the 1970s. L. parvulus is ranked as S2 (state rare).

Description:

Northern Pygmy Clubtail has two black lateral thoracic stripes (T3-T4). Its relative, Southern Pygmy Clubtail, has only one stripe on the side of the thorax (T4) (Paulson, 2011).

There are 14 records in the project database.
