What season do caddisflies emerge?

Summer.

By the time of growth, the earliest emergence in May to July is called "summer call", and its sound is relatively short and weak, with the sound of "giggle giggle giggle ......"; its body is extremely strong and robust, and it can resist cold to a certain extent.

The caddisfly is very strong and has a certain ability to resist the cold, and if it is well protected, it can be overwintered, so the breeders like to keep this kind of caddisfly.

The caddisfly likes to inhabit in the field or crop land, and more often inhabits in the branches of high trees or sunny slopes in high and dry places. Its hind limbs are stout, good at jumping, more agile, but once disturbed, it will jump straight down.

The grasshopper feeds on young leaves of plants, but also eats small insects and fresh beans, leaves and stems. It can chirp during the day and at night, and chirps more frequently during the day. Summer heat period, the more dry and hot weather, it called the more vigorous, chirping sound seems urgent and continuous. When the temperature is low, the call is light and slow, and it likes to climb to the high place of the tree branches to call.

The way to choose a good quality caddis:

The first thing to do is to choose a good quality caddis is to choose one with big and thick wings. The back plane of the bladder is also wide and long. The back plane of the bladder should be spread out with the upper left bladder close to the lower right bladder. There should be no large gaps when closing the bladder, it should be closed tightly and covered tightly.

The tone file and scraper should protrude a bit and the wing veins should be full. The right wing of the upper left bladder should be sufficient to cover the foot in the lower bladder. The larger the bulge (lens) of the lower right bladder, the better. The higher the bladder, the better the bladders should be on the back of the caddisfly and off the belly when it is at rest.

The wider and bigger the bladder wall, the better, no matter it is black caddis or green caddis, the bladder wall should be green, the real black iron caddis or gold caddis (male) front wing characteristics: wing caddis bladder wall should be yellow or light yellow-green.
