Araba Bioscan 30 October to 6 November 2020

Data for the period 30 October to 6 November 2020

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


This was a cold week and very wet. On 1 November, no point in the whole 24-hour period was as warm as midnight at the start.

The moths captured included several of the small oecophorid Hoplostega ochroma (Meyrick, 1886), as well as the first record for the site of Philobota cretacea Meyrick, 1884. This latter species had not been recorded from light trapping at the site.

Thanks to Frans for the springtail identification, Boris Büche on iNaturalist for the Aderidae identification, Nigel Main on iNaturalist for the ant genus identifications, and tonyd on iNaturalist for multiple fly identifications.

The collecting medium was 95% isopropyl alcohol.
