Figure 6 in The Behavioral Ecology of Insect Vibrational Communication
Figure 6. Frequency spectra of vibrational signals (a through f) predicted to evolve in response to different combinations of receiver frequency selectivity and average substrate filtering properties. For example, when the substrate filtering is unpredictable or flat, use of signals containing a broad range of frequencies may ensure that some energy reaches the signaler (a). However, this strategy will only be successful if receivers are also broadly tuned; if receivers are selective for a narrow band of frequencies, signals should likewise be narrowly tuned (b). Use of hosts with different filtering properties (such as lowpass vs. bandpass filters, or bandpass filters with different best frequencies) may favor the evolution of different signals, a process that could contribute to speciation.
Figure 5 in The Behavioral Ecology of Insect Vibrational Communication
Figure 5. Female preference curve for signal frequency compared with the amplitude spectrum of a male advertisement signal for a treehopper (a member of the Enchenopa binotata species complex occurring on the host plant Ptelea trifoliata in central Missouri). (a) Amplitude spectrum of a male advertisement signal that closely matches the mean frequency for the population. The waveform of that signal is shown above. (b) Proportion of females (n = 15) that responded to digitally generated signals that varied in carrier frequency while keeping all other traits at the mean value for the population. Playback stimuli were delivered by means of a magnet attached to the host plant stem and an electromagnet placed 2 millimeters away from the magnet. The stimuli and the female response calls were monitored with a PCB U352B65 accelerometer and U480E09 amplifier connected to a recording computer. Playback intensity was set to the median peak acceleration of the signals of nine males recorded on the playback plant.
Figure 4 in The Behavioral Ecology of Insect Vibrational Communication
Figure 4. Examples of complex vibrational signaling environments. (a) A male treehopper (Heteronotus trinodosus) producing advertisement signals in alternation with another male on the same stem. (b, c) Field recordings from two herbaceous plants in Soberanía National Park, Panama. Each recording contains signals of approximately four insect species, with one species signaling continuously (indicated with number 1 in panel b and number 3 in panel c). Scale bars = 1 second. It is difficult to gain from figures like these the impression one gets, when listening to vibrational signals in plants in the field, of an encounter with a mysterious and alien world of sound.
Figure 1 in The Behavioral Ecology of Insect Vibrational Communication
Figure 1. Prevalence of various signaling modalities among insects that use mechanical communication (categories from Greenfield 2002). The pie chart above shows an estimate obtained by tallying the number of families for which evidence of signaling in any given modality exists. The chart below shows a more speculative estimate obtained by counting the number of species for which such evidence is available; for groups in which reports suggest the use of a modality is widespread, or for which few reports exist but all have found use of a particular modality, we tallied the total number of described species in the group. We excluded instances of detection of incidental cues produced by conspecifics (e.g., we did not count detection of water surface vibrations by gyrinid beetles or of near-field vibrations by culicids and chironomids). We also excluded instances in which the vibration might be perceived through direct bodily contact (e.g., during copulatory courtship). Files with the references used to generate this figure are available on request from the authors. The distribution of signaling modalities among insect orders (phylogenetic tree from Gullan and Cranston 2000) suggests that the use of substrate vibrations for communication may be ancestral for at least some insect groups at the supraordinal level.

Figure 3. Wind as an agent of selection on insect vibrational communication through plants. (a) Hourly wind speeds, averaged over one month, recorded at a weather station in Corvallis, Oregon. Wind speeds were consistently lower in the morning. Wind-speed data were obtained from the AgriMet Program of the US Bureau of Reclamation, Pacific Northwest Region (www.usbr.gov/pn/agrimet/ webagdayread.html). (b) Short-term variation in the amplitude of wind-induced vibrations in a petiole of a black walnut tree, Juglans nigra. (c, d) Amplitude spectra (x ⎯ ± standard deviation) of wind-induced vibrations in petioles of two tree species, J. nigra and Robinia pseudoacacia, showing the predominance of low frequencies and the gradual roll-off at higher frequencies. Wind noise recordings were made at typical positions of treehoppers (Enchenopa binotata) on the two host plants, using a PCB U352B65 accelerometer attached to the leaf petiole and a PCB U480E09 amplifier connected to a Macintosh G3 laptop computer. Maximum wind velocity for these recordings, measured with a handheld anemometer, varied from 1 to 2 meters per second (n = 1 petiole per tree for 10 trees of each species).
A tentative role of vibration-based communication in locust collective behavior
Locusts are renowned for their coordinated locomotion, or collective marching, in which juveniles swarm and walk in a synchronized fashion. While it is generally accepted that vision is the main form of communication enabling this behavior, it is suggested here that mechanical vibrations may also contribute to communication within the group. Using a laser Doppler vibrometer and accelerometer, the substrate vibration signals generated by locust walking, jumping, and coordinated marching were quantified in terms of frequency and amplitude. These mechanical signals were then artificially produced by a vibration generator and directly applied to the mechanical sensory receptors of experimental tethered locusts. A sensory threshold curve of the mechanical response of the locusts was established, in order to quantify and compare their ability to sense specific forms of locomotion, namely: individual walking, jumping, and coordinated group marching. While the vibrations generated by individuals walking in an unsynchronized fashion were below the sensory threshold of the locust, our findings indicate that locusts are capable of sensing the vibration signals generated by locust hopping or by the collective marching of conspecifics. It is suggested that locusts in a swarm may use substrate-borne mechanical vibrations for communication within the group, and that vibration-based communication may have a role in locust collective behavior and coordinated marching.

Figure 6 Audio spectrograms of courtship songs of four species of Anaxipha showing drumming bouts (below 2 kHz) and tegminal sounds (above 4 kHz). Low frequencies (below 2 kHz) were enhanced to better show the low-frequency drumming bouts. A.Anaxipha exigua, dark areas below 1 kHz are drumming bouts; B.Anaxipha tinnulacita, fine, dark lines after 1:05 (min:sec) are the drumming bouts; C.Anaxipha tinnulenta, the dark areas after 5 sec and below 2 kHz are the drumming bouts; D.Anaxipha thomasi, the compact dark areas below 2 kHz are the drumming bouts. The clustered, individual taps between drumming bouts are sounds made by the insect jumping repeatedly and rapidly between echemes during the courtship display. Note that the time scales for each courtship song are different, as each species courtship song length is different and variable.

Figure 7 Examination of the means of the average power of the combined first two and the combined last two taps of drumming bouts in courtship songs ±SD. In nearly all instances, tapping becomes louder during an individual drumming bout within courtship songs across all four species. Numbers closer to the abscissas are louder. a = average of the first two taps, b = average of the last two taps in bouts of four taps or more. * = t-tests comparing the means of first two taps to the last two taps, within each species, showed the p-values were all < 0.0001, showing that the taps are significantly louder at the end of drumming bouts (A. exigua n = 5 songs, 45 drumming bouts; A. tinnulacita n = 4, 29; A. tinnulenta n = 4, 98; A. thomasi n = 5, 75).

Figure 1 A typical drumming bout showing the low-frequency and brief nature of these sounds. The figure is the selection of a drumming bout from a courtship song of A. thomasi showing the selection window spanning from the middle of the first tap to the middle of the last tap. This tapping bout consists of 12 taps.
Data from: Spawning behaviour of Arctic charr (Salvelinus alpinus): spawning synchrony, vibrational communication and mate guarding
A mismatch between male and female gamete release in external fertilizers can result in reduced or failed fertilization, sperm competition and reduced paternity. Here, spawning behaviour of free-living Arctic charr (Salvelinus alpinus) was video recorded, and their reproductive behaviour was analysed. From evaluating 157 spawning events we observed that females mainly spawned with a guarding male and the female and the guarding male synchronized timing of gamete releaseunder sperm competition. Although sneakers spawned with higher synchrony than the guarding male in single male spawning events, the average sneaker released his milt 0.6 seconds after the spawning female under sperm competition. Approximately 50% of the recorded spawning events occurred under sperm competition, where each event included an average of 2.7 males. Additionally, sneakers were more exposed to sperm competition than guarding males. An influx of males, in close proximity to the female, occurred during the behavioural sequences leading up to egg release, but this influx seemed not dependent on egg release, suggesting that something else than gonadal product attracts sneaker males to the spawning female. Just before and during the actual release of gametes the spawning couple vibrates their bodies in close contact and it seems likely that vibrational communication between the spawning couple reveals time of gamete release to surrounding sneaker males. This might explain the relative high level of synchrony in gamete release between the female and the males from both reproductive tactics under sperm competition. Thus, vibrational communication between the guarding male and the female comes with the cost of higher detectability from surrounding males and may represent a "double-edged sword" for the guarding male.
