Authority: (Herrich‑Schäffer, 1851)
Morphological Description
- Wingspan: 10–13 mm.
- Forewings: Generally ochreous‑brown to grey‑brown with a distinctive pattern of darker fascia and a series of small, often indistinct, blackish spots near the termen. The basal area may exhibit a faint metallic sheen.
- Hindwings: Greyish‑white, becoming darker toward the outer margin.
- Sexual Dimorphism: Minimal; both sexes display similar coloration and size, though males may have slightly more pronounced antennal pectination.
Distribution and Habitat
Phalonidia manniana is a Palearctic species with a broad European range. Recorded occurrences include:
- Western and Central Europe (e.g., United Kingdom, Ireland, France, Germany, the Netherlands, Belgium).
- Eastern Europe (e.g., Poland, Czech Republic, Slovakia, Hungary, Ukraine, Russia).
- Extending into parts of the Mediterranean basin and western Asia (e.g., Turkey).
The moth typically inhabits open, herbaceous environments such as meadow edges, waste grounds, roadside verges, and grasslands where host plants are abundant.
Life Cycle and Ecology
- Flight Period: Adults are most commonly observed from late May through July, with peak activity in June.
- Behavior: Nocturnal; adults are attracted to light sources.
- Reproduction: Females lay eggs singly or in small clusters on the host plant’s developing flower heads or seedheads.
- Larval Host Plants: Larvae are polyphagous on low‑growing herbaceous plants, primarily within the family Asteraceae. Documented hosts include species of Inula, Centaurea, Carduus, and Cirsium. Larvae feed within the flower heads, consuming both floral tissue and developing seeds.
- Development: The larval stage occurs from early summer until late autumn. Pupation takes place in a silken cocoon among the detritus of the host plant or in the soil. The species overwinters in the pupal stage, with adults emerging the following spring.
Conservation Status
Phalonidia manniana is not currently listed under any threatened categories on the IUCN Red List. In most parts of its range the species is considered locally common and does not face significant conservation concerns.
