Large heath

Large heath

Coenonympha tullia

A species of Ringlets, Also known as Inornate ringlet

The moths are very different in size and reach a wing span of 27 to 40 mm. They have very variable wing tops, from pale yellowish and ocher yellow to brownish. Mostly on the forewing underside near the tip of a small, brightly knurled eye spot is formed, which often shines on the top. At the leading edge there are sometimes further smaller eye spots. On the darker colored light, dark brown or gray rear wing underside as well usually several white or brightly gerandete black Augenflecken are to be seen with silver point, which can also be missing. Unmistakable feature of the species is there a white irregular and interrupted bandage, which already begins at the front edge of the hind wings. The egg is large, ovate and very finely meshed. It is initially pale yellowish green and later marbled reddish brown. The hairless caterpillar is about 25 millimeters long and has small, yellowish point warts and is tapered backwards. It is light green in Europe with a narrow, dark midline and a narrow upper white-yellow and dark upper bound and a lower broader, pale yellow and sharply delineated line. In North America, it varies from green to olive green to brown and has alternately bright and dark vertical stripes. At the end of the abdomen they carry two small pink lobes, which mark the caterpillars of the eye-butterflies (Satyrinae). The head is green or tan. The pupa is green in Europe and North America with light longitudinal lines and in California green to brown.

Habitat Preferences of Large heath Through Different Life Stages
The eggs of large heath can typically be found on or near host grass leaves where they have been deposited. As caterpillars, they are often located in grassy areas, staying close to the ground among their food plants. Searching for the caterpillar stage may require inspecting these food plants directly for signs of feeding or presence. The pupae are usually well hidden in the grass or low vegetation, making them more challenging to spot; carefully searching through leaf litter or around the base of grasses might be necessary. Adult large heath, on the other hand, are found in meadows, grasslands, and sometimes open woodlands, often when scouting for nectar sources or mates.

Egg Large heath eggs will be laid on or near the host plants they feed upon. Check the undersides of leaves and stems of known host plants in the region to find them.
Larva Large heath caterpillars can be located on their specific host plants. Look for signs of feeding, such as chewed leaves, and inspect both sides of the foliage as well as stems.
Pupal Large heath chrysalids may be hanging from plant stems or concealed in leaf litter or soil near the host plants. Search for them by carefully examining potential pupating sites, taking care not to disturb them.
Adult Adult large heath can be spotted near nectar sources or basking in sunny spots early in the day. They are often found in meadows or fields with abundant flowers. Use binoculars to observe them from a distance, and approach slowly and cautiously to avoid startling them.
