Tree cricket

Females of the wine chicken

The flowers crickets ( Oecanthinae ) are a subfamily of the family of the Real Grilling and thus belong to the order of the long horned grasshoppers ( Ensifera ). Some authors summarize the group as their own family Oecanthidae.

Features

Like other long horned crickets and crickets have flowers grilling extended, adapted for jumping hind legs and a long string-like sensors ( antennas). As with other grilling the elytra are in the flowering grilling flat above the other, and it was mostly the right over the left front wing. However, the appearance of the flowers crickets differs considerably from that of other crickets. The body is mostly translucent green or red-green, rarely dark.

All flowers crickets are thermophilic and are among the hemimetabolic. This means that their larvae and nymphs look very similar to the adult animals, and there is no pupal stage with them.

Communication

The sound production is carried out in the flowering grilling, as with other grilling also about stridulation. Here, a serrated Shrill vein on the underside of the right front wing on the trailing edge of the other front wing is moved back and forth. At the flower grilling exclusively stridulate the males. Make it their forewings to steep. The stridulation is used for area delineation and attraction of females ( Lockgesang ).

The males of some species sing in a natural indentation of a foliage leaf or even in a specially eaten into the leaf opening ( Oecanthus burmeisteri ). The surrounding sheet then acts as an open baffle ( baffle ) which allows the emission of a higher acoustic energy. Otherwise, would generate less airborne sound intensities relative to the size of the animals, relatively low-frequency wing vibrations.

Based on the number of ejected from Oecanthus fultoni within a certain time interval sounds can be concluded that the current air temperature at the location of the animal on the Dolbearsche law.

Reproduction

Once the female has reached a singing with the species-specific Lockgesang male, then the male depends on his wings on. The female climbs over the male and begins at a pit at the wing base a secreted by the male gland secretions record. During this time, the male attaches the spermatophore to the female. Even after mating the course continues on secretion. This will ensure that as many sperm reach and fertilize the egg.
