Older male crickets are considered more desirable by females as they supposedly have established territories. Their practical experience in the field also makes them better providers in the eyes of the female.
The study determined whether or not size, type, and pitch of sound define aggressive intent in males. A parameter was set to measure aggressive intent in males. The study found that an aggressive song represents Resource Holding Potential and is sung to establish dominance.
High short-term repeatability in both frequency and pitch represents aggression. Males significantly alter their aggression according to the perceived resource value during mating calls. Males, isolated from female companionship for four days or more, are likely to be aggressive.
Surprisingly, male crickets did not show the same levels of aggression in terms of food availability. The fighting intent for both food and mating is the same. However, an assault was only witnessed in the presence of females and as a result of prior isolation. Males present a selective response to food and females. They only fight for dominance when in fear of losing mating opportunities. When they detect other males around as competition, their chirping turns into a rivalry sound.
The song is meant to ward off other males to protect their territory and their females. A study by the Zoology department of The University of Michigan observed the aggressive and sexual behavioral patterns in crickets. Male crickets were observed to identify patterns in aggressive encounters to establish dominance.
Most encounters ended with one of the two male counterparts retreating. There are five different levels of aggressive interactions, though. In the following stages, an encounter refers to any physical contact between the two crickets. It includes, but is not limited to, the joining of antennae or engaging in a headlock. The first is the mildest interaction between two males. The contact ends without any physical contact.
There are no signs of established dominance or retreat. A meeting that ends without any apparent signs of aggression is considered the second level. One of the two participants retreats, allowing the other to establish dominance. Aggressive interactions between crickets are of the third level when they result in retreat after mild to moderate one-sided aggression or mild reciprocal aggression. Moderate to intense aggression displayed by both sides counts as fourth level aggressive contact.
Prolonged combat between the opponents is considered the fifth level. Both participants in this combat are considered strong candidates. When an encounter takes place, it could end in several ways. One of the opponents may start courting aggressively.
In an alternate scenario, a challenged cricket may even show signs of reciprocal aggression. When threatened, both crickets may engage in physical contact.
In this case, they may remain interlocked and stand still for several minutes until one of them gives up. Once she finds the male, she lays her eggs on the cricket. When the eggs hatch into larvae, they start feeding on the host body.
The cricket dies within a week. That does not stop them from calling out, though. Males often put their lives at risk in order to find a mate. The males go out of their way to protect their females. Crickets have a wide range of predators, so the risk of them being prey is high. Despite that, male crickets allow the females to take refuge in the burrows before the males do. Their act of chivalry results in higher death rates among their sex. The difference in songs sung by various crickets is subtle.
They vary in pulse number and frequency. Average chirp songs have one to eight pulses with regular intervals in the middle. Courtship songs have faster chirps and varying frequencies, depending on the competition. Chirp rates also vary by species and temperature. Crickets are cold-blooded insects and become more active with rising temperatures.
Because they are nocturnal, they are generally asleep during the day. The sounds these insects produce not only attract mates but predators as well. As a defense mechanism, crickets silence themselves when they hear someone approach. They are hypersensitive to vibrations and noise. Crickets get a warning nerve impulse whenever they hear the slightest sound or feel a vibration.
They immediately quiet down to ward off predators. Crickets are usually brown or black. Because of their colors, they blend in very well with their surroundings. Their camouflaging colors provide them with protection from a lot of predators. What do crickets eat? Crickets are omnivores, which means that they eat both plants and animals other insects , depending upon whatever is available to them.
