Araba Bioscan 12-19 February 2021

Data for the period 12-19 February 2021

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

Notes

This week, I’ve returned to 95% isopropyl as the sampling medium. Once results back from samples collected using both isopropyl and denatured ethanol, it will be easier to decide which to use longer term.

After many weeks during which Ichneumonidae were prominent, there was only one (I think) this week (and also no Blattodea). All the ichneumonid species that have been prominent for some weeks were absent. Compare samples from the last month, for which I have photographed every ichneumonid I found (based on my current identifications, 16, 3, 11 and 12 individuals in the last four weeks).
