Paectes abrostoloides
(Guenée, 1852)
Large Paectes Moth, Sweetgum Defoliator
Paectes abrostoloides is a small in the Euteliidae, first described by Achille Guenée in 1852. have a wingspan of 27–32 mm and are active from April to October across eastern and central North America. The is notable for its larval association with sweetgum trees (Liquidambar styraciflua), earning it the 'Sweetgum Defoliator.'

Identification
Can be distinguished from similar Paectes by examination of male and female genitalia; external wing patterns overlap considerably with and are unreliable for species-level identification. The upward-curved abdominal posture when at rest is a notable behavioral cue. Distinguished from the related P. arcigera by specific genitalic characters.

Habitat
Associated with supporting sweetgum (Liquidambar styraciflua), including deciduous woodlands, forest edges, and riparian areas. are attracted to artificial light sources.
Distribution
Eastern and central United States from Massachusetts south to Florida, west to Arizona and north to Utah. Also recorded from the Antilles and Honduras.
Seasonality
on wing from April to October, with peak activity during summer months.
Diet
Larvae feed exclusively on leaves of Liquidambar styraciflua (sweetgum). feeding habits unknown.
Host Associations

Life Cycle
Complete with , larval, pupal, and stages. Larvae feed on sweetgum leaves. Specific details of site and stage not documented.
Behavior
exhibit a characteristic resting posture with curved upward. ; attracted to light. Larvae are leaf-feeders.
Ecological Role
Herbivore; larvae function as defoliators of sweetgum, potentially impacting tree health during conditions. Role in as prey for likely but undocumented.
Human Relevance
Occasional pest of sweetgum in urban and forest settings; 'Sweetgum Defoliator' reflects this association. Attracted to light traps and frequently observed during National Moth Week events.

Research Context
Related Paectes have been investigated as potential biocontrol agents for Brazilian peppertree (Schinus terebinthifolia) in Florida, though P. abrostoloides itself is not involved in this research.
