Cucullia gnaphalii

A species of Hooded owlets

C. gnaphalii Hbn. (27 e). Like Cucullia xeranthemi, from which it is distinguished by the more rounded orbicular, not 8-shaped; by the absence of a black shade before outer line in submedian fold, while the black line beyond it is thickened and more conspicuous; the outer line being bent at right angles on the fold, its lower half vertical; above vein 4 a black streak from the reniform stigma, interrupted in the middle; a black streak along middle of inner margin; hindwing brownish, the basal half paler, but not nearly so pale as in xeranthemi. Larva deep green; dorsal stripe broad, red-brown; spiracles yellow on an interrupted red-brown streak; head green. The wingspan is 38–46 mm.

Life Cycle of Cudweed
Egg The life of cudweed begins as an egg, which is often round or oval and tiny. The eggs are usually laid in clusters or rows on host plants, and depending on the species, they may vary in color from white to green or yellow.
Larva Upon hatching, the larvae, or caterpillars of cudweed, emerge. These larvae have a worm-like appearance, distinct segmentation, and come in various colors and patterns for camouflage or warning. They possess voracious appetites, focused on eating and growing, undergoing several molts and increasing in size with each stage.
Pupal After growing to a sufficient size, the larva transforms into a pupa. It forms a protective casing or cocoon around itself, and during this stage, the cudweed goes through significant changes internally as its body restructures into the adult form, often within a chrysalis.
Adult The final stage in the life cycle of cudweed is the adult moth. The mature moth emerges with wings that need to dry and expand. Their coloration allows for species-specific identification and mate attraction. They are capable of flight, focusing on reproduction, and do not feed or have limited feeding habits.

How Can You Attract Cudweed
Cudweed caterpillars are typically herbivorous and feed on specific host plants. Identifying and utilizing these plants can serve as an effective lure.

What is the Best Weather to Observe Cudweed
Calm, warm, and humid nights are ideal for attracting adult cudweed, as these conditions are favorable for their flight. For larvae, days without extreme temperatures or strong winds provide better conditions for searching.

How and Where Can You Find Cudweed at Different Life Stages
Egg Cudweed eggs are often laid on the underside of leaves of host plants. Inspect the leaves carefully, especially along veins for tiny, spherical or ovular eggs.
Larva Cudweed larvae, or caterpillars, can be found on or near their food plants. Look for signs of feeding such as chewed leaves, droppings, or the caterpillars themselves along the stem or under leaves.
Pupal Cudweed pupae might be buried in soil, hidden in leaf litter, or attached to the host plant or nearby structures. Searching the ground or examining the crevices and junctions of plants might reveal them.
Adult Cudweed adults are moths that are active at night. Using a light trap near host plants can attract them for easy observation or capture. A white sheet illuminated by a UV light in the evening is a common and effective setup.
