Drepanosiphum oregonensis
Granovsky, 1939
Dark-streaked Maple Aphid
Drepanosiphum oregonensis is a North American described by Granovsky in 1939, commonly known as the Dark-streaked Maple Aphid. It belongs to the Drepanosiphum, which comprises aphids specialized on maple (Acer) plants. The species is currently recognized as a synonym of Drepanosiphum oregonense in some taxonomic treatments. Very few observations exist in biodiversity databases, suggesting it may be uncommon, undercollected, or restricted to specific geographic regions.

Habitat
Associated with maple (Acer) plants, as is characteristic for the Drepanosiphum. Specific microhabitat preferences within maple-dominated environments are not documented.
Distribution
The specific epithet "oregonensis" suggests an association with Oregon or the Pacific Northwest region of North America. However, precise distribution records are sparse. GBIF reports no distribution records. iNaturalist contains 4 observations, though specific locality data is not provided in the available sources. The ' actual range remains poorly characterized.
Diet
Feeding on phloem sap of maple (Acer) , consistent with the -level specialization of Drepanosiphum aphids. Specific maple species for D. oregonensis are not documented.
Host Associations
- Acer - primary -level association inferred from Drepanosiphum ; specific Acer unknown

More Details
Taxonomic Note
The Catalogue of Life lists Drepanosiphum oregonensis as a synonym of Drepanosiphum oregonense, indicating taxonomic uncertainty or recent reclassification. The GBIF match also identifies this as a synonym. Users should verify current accepted when conducting research.
Data Deficiency
This is extremely poorly documented in biodiversity databases. With only 4 iNaturalist observations and no GBIF distribution records, basic biological information including appearance, seasonality, and precise distribution remains unknown. This likely reflects a combination of genuine rarity, restricted distribution, undercollection, and taxonomic confusion with related species.
