Diplotaxis lengii
Fall, 1909
Diplotaxis lengii is a small scarab beetle in the Scarabaeidae, Melolonthinae. The Diplotaxis contains numerous small , many of which are attracted to lights at night. This was described by Fall in 1909 and is known from the southern United States, particularly Louisiana and Texas. Members of this genus are often observed congregating on low vegetation, apparently to intercept trails in search of mates.

Identification
Small scarab beetle in the Diplotaxis. -level identification within this genus typically requires examination of male genitalia or other detailed morphological characters not visible in field observations. The genus can be recognized among small scarabs by its melolonthine characteristics combined with small size and typical body form.
Habitat
Associated with sandy or open in the southern United States. Related Diplotaxis are frequently found in dune systems, sand prairies, and open rangeland with scattered vegetation.
Distribution
Nearctic region: United States (Louisiana, Texas).
Seasonality
have been observed in June, suggesting late spring to early summer activity. Many Diplotaxis are and attracted to lights.
Behavior
Nocturnally active. of related Diplotaxis have been observed congregating on low plants to "catch" trails in search of mates. Attracted to blacklights and other artificial light sources.
Ecological Role
likely feed on pollen or other plant materials; larvae of melolonthine scarabs typically develop in soil, feeding on roots or decaying organic matter.
Similar Taxa
- Other Diplotaxis speciesNumerous occur in the same region and share similar size, shape, and ; require genitalic dissection for reliable separation.
- Other small melolonthine chafersSimilar size and light-attracted ; identification requires detailed examination of tarsal structure, antennal , and other subtle characters.
More Details
Taxonomic note
The epithet 'lengii' honors an individual with the surname Leng, likely J. Hamilton Leng, an early American coleopterist.
Collection note
As with many small scarab , voucher specimens with properly dissected and mounted genitalia are typically required for definitive identification beyond level.
