Insects

Name: 밀잠자리 (Mil jamjari)
Scientific name: Orthetrum albistylum speciosum (Uhler)
Distribution: Korea, China, Japan, Taiwan

This dragon fly has an average abdomen length of 35 to 40 millimeters and a wingspan of 40 to 45 millimeters. The back of the head is black on the males and yellow on the females. The frontal tubercle is black. The color of the forehead, ante-clypeus and upper lips are all glossy gray-black on the males and yellow on the females. Three black stripes can be found along the sides of the abdomen.

Ecology: The adults can be observed from the middle of April to the middle of October around the flatlands as well as wetlands, rice paddies and ponds surrounded by aquatic plants. After mating, females are protected by the males. Under this protection, the females spawn on the water surface around swamps or reservoirs.

The needles are dark green, very tough and can be twisted. The tip is pointy. This monoecious tree gives bloom to a purple-brown male flower and an egg-shaped female flower. The fruit is an egg-shaped oval cone. The central part of the seed breaks outward, and there is no part of it that protrudes. The seeds slowly turn greenish-brown.

Print: black
Inedible

This inedible mushroom, known as a trooping crumble cap, grows in multiple clusters from rotting branches of dead trees, stumps and wood buried underground. The pileus has an average diameter of 1 to 1.5 centimeters and as it grows widens from being egg-shaped, semi-round and finally to being bell-shaped. The surface is white or gray, covered with small hairs.

The pleats change color from white to black and the cap can be as large as 2 to 3.5 centimeters. The color is white or translucent. The surface is covered by small hairs. It is very fragile.

Herbs & Flowers

Name: 십자고사리 (Sipja gosari)
Scientific name: Polystichum tripteron (Kunze) C. Presl
Full bloom: May
Distribution: valleys nationwide

This fern grows around valleys in the mountains. The short subterranean roots grow upward in every direction. The stipe is 10 to 30 centimeters long. The squama sticks close to the axis but falls off easily. The leaf blades can reach a maximum size of 50 centimeters. It develops a leaf with pinnate scales. The squama remains at the back of the leaf for a relatively longer period of time. The sorus develops from scattered pinnules and the indusium falls off early in the season.
