Larvae of Enallagma davisi and E. recurvatum have round gill tips similar to E. minusculum but final stadia are significantly larger (total length 11.4–13.8 mm for davisi and recurvatum combined vs. 9.5–9.7 mm for minusculum) and the lateral carinae of abdominal segments 2–7 have distinct stout setae. The prementum of E. davisi (length 1.85–2.30 mm, width 1.56–1.80 mm; n = 10) is slightly larger than that of E. recurvatum (length 1.75–1.85 mm, width 1.48–1.53 mm; n = 5). The cerci of E. davisi in lateral view are wider than long in males and about as wide as long in females; in E. recurvatum the cerci are longer than wide in both sexes.
