Araba Bioscan 15-22 January 2021

Data for the period 15-22 January 2021

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


This week’s sample included three individuals of a Ulonemia (Hemiptera: Tingidae) species that seems not to be Ulonemia burckhardti, which had already been recorded. According to Shofner 2018 that species has “metasternal carinae straight, parallel, width equal to mesosternal carinae”, whereas the new insects show significant widening of these carinae relative to the mesosternal carinae.

A Camponotus specimen in the sample was heavily infested with small dark discs, apparently the spores of a fungus, most likely Myrmicinosporidium durum, although all records of this parasite to date seem to be from the northern hemisphere.

The sample also included the first plume moth for the project, one individual of Stenoptilia zophodactylus (Duponchel, 1840), a species of near-global distribution.
