Megaloptera; doesn't that sound like something Godzilla should be fighting?
Por otro lado, los adultos voladores de ciertos grupos, como por ejemplo Odonata, Trichoptera y
Megaloptera, se preservan en seco (guardados en sobres transparentes o montados en alfileres, segun el grupo) o montados en laminas fijas (algunas familias de Diptera).
We collected a total of 10,723 individuals, included in 86 families (Table 3), distributed in five classes: i) Insecta (eight families belong to Ephemeroptera, nine to Odonata, one to Plecoptera, 12 to Hemiptera, 10 to Trichoptera, one to
Megaloptera, 14 to Coleoptera, 16 to Diptera, and one to Lepidoptera), ii) Maxillopoda (two families belong to order Decapoda, one to Amphipoda, and one to Isopoda); iii) Gastropoda (one family belong to Unionida order, one to Veneroida, two to Basommatophora, four to Neotaenioglossa; iv) Turbellaria (one family belonging to Tricladida order); and v) Acari (the order Hydrachnidia).
Large numbers of adult
Megaloptera are seldom seen in nature because they are short-lived, secretive, and many species are nocturnal (Flint et al., 2008).
Taxones residentes Ordenes y familias de especies de insectos acuaticos encontrados: Coleoptera (larvas y adulto de; Curculionidae, Dytiscidae, Haliplidae, Hydrochidae, Hydrophilidae, Limnichidae, Luthrochidae y Noteridae), Ephemeroptera (larvas), Hemiptera (larvas y adultos de; Belostomatidae, Corixidae, Hebridae, Hydrometridae, Gerridae, Macroveliidae, Mesoveliidae, Naucoridae, Nepidae, Notonectidae, Veliidae),
Megaloptera (larvas de Corydalidae), Plecoptera (larvas), Trichoptera (larvas) Odonata (larvas).
Several orders contributed to the predatory feeding group including Odonata, Plecoptera,
Megaloptera and Hemiptera.
In order to simplify analysis, the following dietary categories were used: molluscs (Mollusca), leeches (Hirudinea), zooplankton, crustaceans (Crustacea, represented solely by waterlouse Asellus aquaticus), mayflies (Ephemeroptera), caddisflies (Trichoptera), chironomid larvae and pupae (Chironomidae), dipterans (Diptera, except Chironomidae), terrestrial insects, other (Odonata, Heteroptera,
Megaloptera, Coleoptera), fish eggs, fish fry and detritus (detritus, sand and macrovegetation residue; not included in analysis).
The three most-abundant aquatic invertebrate taxa collected were Crustacea (n = 3,568), Ephemeroptera (n = 2,080), and Heteroptera (n = 2,038) while only a few individuals of
Megaloptera (n = 2), Arachnida (n = 14), and Plecoptera (n = 21) were captured (Table 1).
