Neotelphusa sequax

Small size (11–14 mm wingspan) and July flight period are key features. Distinguishable from congeneric species by genitalia examination; external morphology requires specialist verification. Association with Helianthemum host plants supports identification.

Small moth with wingspan of 11–14 mm. Specific wing pattern details not documented in available sources.

Habitats supporting host plants Helianthemum nummularium and Helianthemum oelandicum, which include calcareous grasslands, rocky slopes, and open dry habitats in Europe.

Native to most of Europe; recorded from Belgium (Antwerpen, Liège, Luxembourg, Namur provinces). Introduced and established in North America.

Adults active in July. Larval stage timing not specified in sources.

Larvae feed on Helianthemum nummularium and Helianthemum oelandicum (Cistaceae). Adult feeding habits unknown.

• Helianthemum nummularium - larval food plantCommon rock-rose
• Helianthemum oelandicum - larval food plantHoary rock-rose

Complete metamorphosis with larval stage on host plants. Specific details of pupation and overwintering stage not documented.

Herbivore on rock-rose species; contributes to nutrient cycling in calcareous grassland ecosystems.

No significant economic or cultural importance. Presence may indicate intact calcareous grassland habitat.

• Other Neotelphusa speciesSimilar size and general appearance; require genitalia dissection or molecular analysis for definitive identification
• Other small GelechiidaeOverlap in size and habitat; host plant association and flight timing help distinguish N. sequax
