The #dockbug #Coreus #marginatus (#Coreidae) is distributed from Europe to Asia. In #CentralEurope, it undergoes one generation per year, with the adults spending their #winter #diapause in hidden places. From October onwards, it can be found e.g. on the underside of #deadwood, as seen here in #Berlin's park Rehberge. T. O. Markova et al. (2020) did studies on the ecology of the #FarEast #subspecies C. m. orientalis.

The dock bug Coreus marginatus (Coreidae) is common in Europe. Adults feed on seeds in different food plants, while the five nymphal instars suck on leaves and other plant tissue. In autumn, when the meadows might be still having a few blooming plants, an insect emptyness can increasingly be observed. It is the time, when many of them can already be found in their winter quarters, where they spend their diapsuse during the cold season. Only a few insects can be winter active, e.g. some stoneflies. The dock bug overwinters as adult in leaf litter or deadwood. I found this specimen on the underside of deadwood in a small forest area. © Stefan F.

@flypapers

The potential for lab fly husbandry are high:

"By late August, most adults are in diapause and reproduction ceases. Like many species of Drosophila in temperate regions, there may be only one generation produced per year. This is likely facilitated by the ability to diapause."

Imagine enabling a Drosophila melanogaster to "diapause" in the freezer instead of having to actively maintain their populations by flipping their bottles into new food every two weeks.

The savings by the Bloomington Drosophila Stock Center alone would be huge.

How do insects count time in the cold? Toxopeus et al. showed that the duration of diapause (winter dormancy) can be modelled in the apple maggot fly using principles of physiological time, assuming that diapause development rate is temperature sensitive.

Moin liebe Gemeinde,
es war ein schönes langes Wochenende da ich den Montag blau gemacht hab in der Dialyse 😁. Das wird wohl über das Jahr häufiger passieren sowie es wird beim nächsten Mal zwei Tage blau gemacht denn Ziel ist es eine Woche ohne Dia mal aus zu kommen.
