This study determined the first complete mitochondrial genome of a damselfly, Euphaea formosa (Insecta: Odonata: Zygoptera), and reconstructed a phylogeny based on thirteen protein-coding genes of mitochondrial genomes in twenty-five representative hexapods to examine the relationships among the basal Pterygota. The damselfly's mitochondrial genome is a circular molecule of 15,700bp long, and c...

The recently completed Odonata database for California consists of specimen records from the major entomology collections of the state, large Odonata collections outside of the state, previous literature, historical and recent field surveys, and from enthusiast group observations. The database includes 32,025 total records and 19,000 unique records for 106 species of dragonflies and damselflies...

T H E genetics of sex-limited polychromatism in natural populations has been Investigated in only a few animals (see review by FORD 1961), none of the known instances including Odonata (damselflies and dragonflies). It is the purpose of the present paper to report the results of a breeding study of female dichromatism in Ischnura damula. This appears to be a case of balanced polymorphism, but i...

The aim of this project was to obtain a baseline understanding and investigate the concentration of mercury (Hg) in the tissue of terrestrial arthropods. The 4-month sampling campaign took place around Monterey Bay, California. Total mercury (HgT) concentrations (x ± SD, dry weight) for the captured specimens ranged from 22 to 188 ng g(-1) in the Jerusalem crickets (Orthoptera: Stenopelmatidae)...

forty eight species of odonata families, including libellulidae (23 species), aeschnidae (7species), gomphidae (5 species), cordulegastridae (1 species) from suborder anisoptera and euphaeidae (1species), calopterygidae (1 species), lestidae (3 species), platycnemididae (1 species) and coenagrionidae (6species) from suborder zygoptera were collected from 46 sampling sites in iran between early ...

Risiophlebia guentheri sp. nov. (holotype: Cambodia, Mondulkiri Province, Dak Dam village environs, a tall grass forest swamp, 12°25' N 107°19' E, ~780 m a.s.l., 16 June 2014, RMNH), the second species in its genus, is described from Central Plateau of the Annamese Mountains. The new species is most probably separated from R. dohrni by a 1000-km gap of the range of the genus in Thailand and mos...

In total 20 species of aquatic insects have been recorded from a weed infested pond. Odonata was numerically the most abundant group constituting of 54% of the total aquatic insects even though these belonged to three species. Coleoptera though constituted only 22% of aquatic insects had 10 species. Urothemis signata and Ranatra filliformes were eudominant and dominant species respectively. Hyd...
