Abdomen. Lab: 24.00–27.00mm (M); 24.52–25.88mm (F). LcaS3: 0.0008 –0.0011 mm (M); 0.0009 – 0.0012 mm (F). LclS3: 0.0014 –0.0022 mm (M); 0.0019 –0.0021 mm (F). Lecv-clS3: 0.0014 –0.0019 mm (M); 0.0013 –0.0015 mm (F).

Caudal appendages. Las: 0.0014 –0.0018 mm (M); 0.0006 –0.0011 mm (F). Poas: 0.0009 –0.003 mm (M); 0.0015 –0.0018 mm (F). Anas: 0.003 –0.006 mm (M); 0.003 –0.005 mm (F). Ddas: 0.002 –0.005 mm (M). Epl: 0.0009 –0.0012 mm (M); 0.003 –0.006 mm (F). Pritchard and Smith (1956) used the caudal appendage length to differentiate the E. collocata and E. simplicicollis larvae. Costa and Pujol-Luz (1993) found that the cercus length exceeds half of the epiproct length.

Larva. Pritchard and Smith (1956) mention the character “lateral anal appendages two-thirds as long as superior appendage”, to differentiate the species. According to Costa and Pujol-Luz (1993) the number of premental or palpal setae has not been recorded, and the cercus is between 1/2 and 2/3 of the length of the epiproct.

Remarks. The label attached to the holotype says “TYPE 1871”, however the species description was published in 1861.

Biology. In Sutter Co. (California), E. collocata adults feeds on Anopheles freeborni Aitken ( Diptera : Culicidae ) mosquitoes in rice crops (Yuval and Bouskila 1993). A high percentage of attacks on mosquitoes were documented at sunset when mosquitoes gathered in copulatory or postcopulatory swarms (Yuval and Bouskila 1993). Collection labels indicate that E. collocata also feeds on specimens of Syrphidae ( Diptera ), antlions (Neuroptera) and Hetaerina vulnerata Hagen in Selys ( Odonata : Calopterygidae ). Manolis (2003) mentioned that E. collocata exhibit a territorial mating system, which was corroborated by Wong-Muñoz et al. (2011) who also found that emergence of the largest individuals occur at the end of the mating season.

Distribution. Canada to Mexico ( Fig. 31 View Figure 31 ), between 30–2286 m. asl.
