Araba Bioscan 4-11 December 2020

Data for the period 4-11 December 2020

See the Araba Bioscan Project page for background information on the project and methods.

Notes

The week included a few cooler days and biomass in the trap was lower than the previous two weeks.

Photographs this week include several species ichneumonoid wasps that resemble others caught in recent weeks, but also many species not previously caught or photographed.

One of the cicadas caught this week and last week has been identified by David Emery as Yoyetta robertsonae Moulds, Popple & Emery 2020. The type locality for this recently described species is within meters of the Malaise trap. See the paper here: A new species of Yoyetta Moulds from south-eastern Australia with notes on relationships within the Yoyetta tristrigata species group (Hemiptera, Cicadidae, Cicadettini).
