About Eucrostes indigenata (de Villiers, 1789)
Eucrostes indigenata is a moth species belonging to the Geometridae family, first formally described by Charles Joseph Devillers in 1789. This moth is distributed across the Mediterranean region, with its inland range extending as far north as North Macedonia and Hungary. One subspecies, Eucrostes indigenata lanjeronica, occurs in southern Spain and Algeria.
Males of this species have a wingspan of 14 to 16 millimeters, while females have a larger wingspan of 18 to 20 millimeters. The species produces two to three generations annually. Adult moths are active between April and October across most of its range; on Malta, adult activity has been recorded as late as the beginning of November. The caterpillar larvae of Eucrostes indigenata feed on plants in the genus Euphorbia, specifically Euphorbia spinosa, E. pinea, E. cyparissias, E. virgata, and E. platyphyllos. This species overwinters in its larval stage.
