Plusia putnami

A species of Plusia, Also known as Putnam's looper

Plusia putnami, the Lempke's gold spot or Putnam's looper moth, is a species of moth of the family Noctuidae. It is found in the Palearctic realm, from Japan and eastern Siberia to Fennoscandia, Great Britain, and France. In North America, it ranges from Newfoundland and Labrador to central Alaska and the interior of British Columbia, south to Pennsylvania, Washington, north-eastern California, and in the Rocky Mountains to Utah and Colorado. The wing pattern differences between putnami and Plusia festucae are not constant. Genitalic genital dissection is needed to differentiate these two species. The wingspan is 32–42 mm.

When is the Best Time to Observe Lempke's gold spot
The most suitable time to find adult lempke's gold spot is during the night when they are active and attracted to light sources. Larval stages should be searched for during the daytime when they are feeding on host plants.
Rectangle
What is the Best Weather to Observe Lempke's gold spot
Warmer nights with little wind and no rain are ideal conditions for locating adult lempke's gold spot, as they are more likely to be active in these conditions. During larval stages, look for lempke's gold spot when the weather is conducive to the growth of their host plants, which is typically during warmer, moist conditions.

How and Where Can You Find Lempke's gold spot at Different Life Stages
Egg Lempke's gold spot eggs can often be found on the underside of leaves of the host plants. To locate them, carefully inspect the foliage by turning leaves over and looking for small, spherical, or oval objects that are commonly laid in clusters.
Larva Lempke's gold spot larvae (caterpillars) are primarily leaf feeders and can be found on or near their specific host plants. Search for signs of feeding damage on leaves and inspect both the upper and lower surfaces of foliage for caterpillars.
Pupal Lempke's gold spot pupae can be challenging to locate as they may be underground or camouflaged within the environment. Look for them in soil, leaf litter, or crevices near the host plants where larvae were found.
Adult To find adult lempke's gold spot moths, use light traps or sheets illuminated by a strong light source at night, as they are attracted to light. Sweet bait traps using molasses, fruit, or wine can also draw them in.

Hurt Plant

When lempke's gold spot larvae feed, they chew through plant tissues, specifically targeting leaves. This infestation results in ragged foliage, with holes and missing sections, which can compromise the plant's ability to photosynthesize and, therefore, its overall growth and vigor.
