“…If this were the case, we thought we might see some indication in the shape of the 20E titer curve of R. milleri since ecdysone along with juvenile hormone has a central role in the control of developmental events in insects (Edgar 2006;Richards 1981). It had been suggested earlier that some of the changes in cocoon building behavior within the Lepidoptera could result from the timing of hormone release (Giebultowicz et al 1980;Sehnal et al 1981). …”

Developmental ecdysteroid titers and DNA puffs in larvae of two sciarid species, Rhynchosciara americana and Rhynchosciara milleri (Diptera: Sciaridae)

et al. 2015

Ecdysteroid titers, developmental landmarks and the presence of prominent amplifying regions (DNA puffs) have been compared during late larval to pupal development in four groups of Rhynchosciara americana larvae and in R. americana and Rhynchosciara milleri. Three prominent DNA puffs (B2, C3 and C8) expand and regress sequentially on the rising phase of the 20-hydroxyecdysone (20E) titer in R. americana as a firm, cellular cocoon is being constructed. A sharp rise in 20E coincides with the regression of these puffs. The shape of the 20E curve is similar in R. milleri, a species that does not construct a massive cocoon, but the behavior of certain DNA puffs and their temporal relationship to the curve differs. Regions corresponding to B2 and C3 can be identified in R. milleri by banding pattern similarity with R. americana chromosomes and, in the case of B2, by hybridization to an R. americana probe. A B2 puff appears in R. milleri as the 20E titer rises but remains small in all gland regions. A puff similar to the R. americana C3 puff occurs in posterior gland cells of R. milleri (C3(Rm)) after the B2 puff, but this site did not hybridize to R. americana C3 probes. C3(Rm) incorporated (3)H-thymidine above background, but showed less post-puff DNA accumulation than C3 of R. americana. R. americana C8 probes hybridized to a more distal region of the R. milleri C chromosome that did not appear to amplify or form a large puff. These differences can be related to developmental differences, in particular differences in cocoon construction between the two species.

“…Gregarious behavior is not uncommon in the Sciaridae (Pratt 1899;Steffan 1974;Eberhard and Flores 2002;Shin et al 2013;Sutou et al 2011). According to Shin et al (2013), it is most frequently observed in larvae of the Sciarinae and Chaetosciara groups.…”

“…The Holarctic fauna has been divided into sixteen species groups (Menzel & Mohrig 2000), but these have been formed mainly based on general similarity. A recent phylogeny based on molecular characters challenges even the monophyly of the genus (Shin et al 2013). …”

“…nov. resembles Scatopsciara (Xenopygina) vinea Rudzinski & Baumann, 2013, but differs in having a simpler tegmen and a different placement of the gonostylar megasetae. In a molecular phylogenetic analysis, the Corynoptera vagula group of species appeared close to species of Scatopsciara Edwards (Shin et al 2013). In this analysis, no species of Scatopsciara (Xenopygina) Frey, 1942 was included.…”

Four species of Bradysia Winnertz (Diptera, Sciaridae) from the Northern Holarctic are described and illustrated for the first time: Bradysia bigeminata sp. nov. (Finland, Canada), B. falciceps, sp. nov. (Finland, Canada), B. oelandica sp. nov. (Sweden) and B. plusiospina sp. nov. (Finland). A few Bradysia species, described previously and now found in Northern Europe, are also redefined and illustrated.
