Type material. Not examined.

Diagnosis. Thorax green, and dorsum of abdomen green with black dorsal bands (female and sexually immature male), or thorax and abdomen pruinose blue (mature male). McVey (1985) provides information about rates of color maturation in relation to age, diet, and temperature in males of this species. Abdominal appendages are white. Basal area hyaline. Posterior lobe of vesica spermalis absent. Hook is bilobed and not perpendicular to the longitudinal axis of the vesica spermalis ( Fig. 18 View Figures 18–25 ), and the lateral lobe is extended more posteriorly than the medial lobe. Cornua is parallel with respect to the transversal axis of the vesica spermalis, with lobes fused to apex, and not covered by lateral lobes in lateral view ( Fig. 20 View Figures 18–25 ). Lab ≤ 30mm.

Larva. Bick (1941) mentions 13 larval instars, a total larval period of 113 days, and an average hatching time as 11.6 days. The small and robust larvae of Erythemis simplicicollis are habitat generalists. They can inhabit swamps, marshes, ponds, lakes, reservoirs and small pools of creeks where they live under the detritus, feeding on tadpoles ( May and Baird 2002; Relyea 2003). Osburn (1906) listed E. simplicicollis larvae living in “slightly salt water”, Wright (1943) reported E. simplicicollis larvae in Mississippi River delta and central Gulf Coast salt marshes in brackish areas of varying salinities (14–57% seawater), Bick et al. (1953) found E. simplicicollis larvae associated with naturally acid streams in southern Louisiana, and Smith and Smith (1995) exposed larvae to six salinities (0–80% seawater) and found that larvae survived for at least 24 h.However, survival time and eclosion significantly decreased at salinities above 20% with only 50% of the larvae emerging at that those higher concentrations (Smith and Smith 1995). Also, little development occurred at salinities of 60% and 80%, suggesting that increasing salt concentration could produce physiological stress on the larvae. Catling (2005) found E. simplicicollis as indicator of higher water quality. Both temperature and time of day influence the occurrences and frequencies of ventilation in larvae of this species, under constant temperature conditions, the vertical migration has its highest peak during photophase and its lowest during dark phase ( Cofrancesco and Howell 1982). According to Morin (1984), the larvae are eaten by fish, compete for food with larvae of Tramea lacerata Hagen (Libellulidae) (Wissinger and McGrady 1993). Larger larvae of E. simplicicollis attack and predate on Hyalella (Crustacea) amphipods ( Cothran 2008).

Remarks. The paratypes of E. simplicicollis were included in the Say’s paratypes collection, but most of his collection is known to have been lost.

Biology. Erythemis simplicicollis adults has been sigth in swarms (Paulson 1966), trapped from light traps (Wright 1944; Frost 1975), and Harrison and Lighton (1998) found that, under laboratory conditions, they are even able to fly with low concentrations of oxygen. E. simplicicollis may to have one, two or several generations per year depending of the climatic conditions ( Montgomery 1980; Harrison and Lighton 1998). This species usually prefer to perch on exposed logs or rocks (Robey 1975) and their sexual recognition is based on visual cues of body coloration ( Andrew 1966). Males are territorial, exhibiting intraspecific flight pattern when two males are in the same area ( Currie 1963), and showing interspecific aggression toward males of Pachydiplax longipennis (Burmeister) ( Baird and May 2003) . McVey (1988) found that lifetime reproductive success was highly variable, suggesting that this variation is important for selection between both sexes, especially when males are territorial ( Koenig and Albano 1987). After mating (which is not preceded by courtship behavior), the male tries to prevent other males from mating with his female or female may mate with different males in one day and store sperm to fertilize their eggs for several days, however, McVey and Smittle (1984) found that the last male in copulate fertilizes the up to 95% of the eggs.

According to collection labels, adults of E. simplicicollis feeds on females of the same species, as well as other Libellulidae (Odonata) such as Celithemis ornata (Rambur) , Perithemis tenera (Say) , and Orthemis ferruginea (Fabricius) , Coenagrionidae (Odonata) such as Enallagma weewa Byers , and Araneae (Arachnida) such as Leucauge argyra (Walckenaer) . E. simplicicollis also hunts Diceroprocta delicata (Osborn) ( Hemiptera : Cicadidae ) (Sanborn 1996), caterpillars of the noctuid moth Helicoverpa zea (Boddie) ( Bell and Whitcomb 1961) and Phidippus pulcherrimus Keyserling ( Araneae : Salticidae ) ( Edwards 1980; 1987). In New York ( USA), Olberg et al. (2000) found that 97% of prey-capture flights by E. simplicicollis males ended in successful captures. On the other hand, some birds ( Calvert 1893), fish and Asilidae (Diptera) such as Promachus hinei Bromley ( Chatfield 2011) may feed on E. simplicicollis . Adults of E. simplicicollis are parasitized by Actinocephalus (Koern.) and Geneiorhynchus Schneider (Eugregarinorida: Actinocephalidae ) ( Locklin and Vodopich 2010), the presence and abundance of these parasites appear to be independent of season and do not affect the host fitness characters ( Locklin and Vodopich 2009; 2010), but in central Texas ( USA), the same authors found that parasite prevalence was biased towards males because of behavioral and environmental aspects that influenced them. Painter et al. (1996) found that repeated applications of Bacillus thuringiensis israelensis on E. simplicicollis , did not affect development, morphology or their flight capability. Recently, a novel adipokinetic hormone (neuropeptide) of corpora cardiaca ( Gäde and Kellner 1999; Gäde et al. 2011), and one Cyclovirus new species, were found in E. simplicicollis adults (Rosario et al. 2012).
