These wetlands also had high densities of Anisoptera (Anax, Somatochlora), Trichoptera (Trianenodes, Ptilostomis), and
Caenis. MC2 lacked Coleoptera and Sigara.
Vout 2007:15-16; or his lack of reference to the influence wielded by Vespasian's mistress
Caenis (recorded at Cass.
Low hydraulic conditions and high level of physicochemical variables of lower sites were associated with the mayfly specie
Caenis ludicra, the watermites Atractides spp., Torrenticola Columbiana and Dodecabates dodecaporus, the trichopteran specie Metrichia spp., and oligochaetes (Figure 2b).
Other groups (Ceratopogonidae, Hirudinea, Hydrachnidia, Sphaeriidae, Asellus aquaticus, Sialis lutaria,
Caenis sp., various Trichoptera) were much rarer.
Good dry fly sport in the evenings with Sedges the best of the larger patterns, and small white duns are attracting fish that are focussed on
caenis.
Among the other macrobenthic and pseudomeiobenthic groups, three taxa were the most frequent in the samples: the crustacean Asellus aquaticus (8 sites, in the lagoons and lakes), the ephemeropteran
Caenis sp.
Based on rank abundance, Cheumatopsyche spp., Calopteryx maculata, Polypedium spp.,
Caenis spp., Stenelmis spp., Cricotopus/Orthocladius group, Tanytarsus spp., Ceratopsyche cheilonis, and Thienemannimyia group were found at more than 50% of the sites.

Caenis, a woman from Thessaly, who upon her request was changed by Neptune into the man Caeneus.
The story of the Roman Emperor Vespasian and his mistress Antonia
Caenis fascinated Lindsey, and, given the lack of information about Antonia, she decided to turn it into a novel.
Dominant macroinvertebrates collected at greater than 70% of the sites were:
Caenis sp., Stenonema femoratum, Lirceus lineatus, Physella integra 54 species from 11 major taxa were collected overall, with highest diversity in the smallest order tributaries.
