Host plants:
The larvae are supposed to feed on Launaea arborescens and Schizogyne sericea, perhaps also on other Asteraceae. I recorded them on Lotus sp. in El Hierro (December 2018).
Habitat:
Microloxia simonyi inhabits dry and warm habitats such as rocky slopes or ravines (barrancos).
Life cycle:
Microloxia simonyi is probably found year-round. The adults are strongly attracted to light. I found them at an illumined building in La Gomera in Valle Gran Rey (February 2013).
Remarks:
Microloxia simonyi is endemic to the more western Canary Islands such as Tenerife, El Hierro or La Gomera.
Hints on determination:
Microloxia simonyi is less intense green than Microloxia schmitzi.
