Araba Bioscan 20-27 November 2020 (Original location)

Data for the period 20-27 November 2020

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


This was the final week operating a trap at the original location. A second Malaise trap was run in parallel this week around 10 m away and caught a much wider range of species – see the following post.

There was a swarming of termites on Saturday 21 and Sunday 22 November and the bulk of insects in this trap were from this event.

The collecting medium was 95% isopropyl alcohol.
