“…Although frog-biting midges have generated much interest for their unusual phonotactic behavior in recent years (Amaral & Pinho, 2015;Bernal et al, 2006;Borkent, 2008, ;Borkent & Grafe, 2012), many aspects of their interaction with anurans and the selective pressures they exert on their hosts remain poorly studied. Costs imposed by frog-biting midges on blood hosts could be substantial, ranging from irritation (indicated by defensive behaviors) and loss of blood (possibly substantial (Camp, 2006)) to an increased risk of infection with pathogens (Meuche, Keller, Ahmad Sah, Ahmad, & Grafe, 2016).…”

The sound of a blood meal: Acoustic ecology of frog‐biting midges (Corethrella) in lowland Pacific Costa Rica

et al. 2019

Animal communication systems are often exploited by eavesdropping antagonists, especially predators and ectoparasites. Female frog‐biting midges (Diptera: Corethrellidae) are known to use male anuran advertisement calls to locate their blood hosts, frogs. Here, we use acoustic midge traps broadcasting synthetic and recorded calls to identify those frog call parameters that affect midge attraction. At our study site in Pacific lowland Costa Rica, we found that overall midge attraction was influenced by both spectral and temporal acoustic parameters. Low dominant frequencies (below 1 kHz) and short pulse durations (between 125 and 500 ms) attracted the highest numbers of midges in tests with synthetic sinusoidal pure tones. These preferences partially explained the relative attractiveness of the advertisement calls of ten local frog species. The advertisement calls of the common and widespread Giant Bullfrog, Leptodactylus savagei (Anura: Leptodactylidae), attracted by far the largest number of midges, suggesting that this frog species might be a key resource for frog‐biting midges in Costa Rica. Although we found that calls of different frog species attracted different midge species/morphospecies in statistically different proportions, acoustic niche differentiation among midge species appeared to be moderate, suggesting either a limited degree of host specialization or the use of additional short‐range, that is, chemical, host recognition cues.

“…Characters and states follow Borkent (), from which most characters and character states were taken. Data from nine subsequently described species were scored according to Borkent & Grafe () and Amaral & Pinho (). One species, Corethrella feipengi Yu, Huang & Zhang, 2013, was omitted due to difficulties in assessing character states from the description (Yu et al , ).…”

“…Together with members of two genera of Culicidae (Borkent & Belton, ; Toma et al , ), they are unique among blood‐feeding dipterans in initially locating their hosts by sound rather than by chemical or visual cues, being attracted to the male mating calls (Bernal et al , ; Borkent, ). The family comprises 107 described recent species and seven fossil species, which are all assigned to the single genus Corethrella Coquillett (Borkent, , ; Borkent & Grafe, ; Yu et al , ; Amaral & Pinho, ). Most species are known from tropical regions, although they extend into Japan, south Sakhalin, southern Canada and temperate parts of New Zealand.…”

Species in the genus Corethrella Coquillett, the only genus in the family Corethrellidae, feed on the blood of frogs and toads and are unique among Diptera in locating their hosts by sound. Their fossil record goes back to the Cretaceous and comprises seven previously described species from various amber deposits. Herein, we present the first records of Corethrella from Late Eocene Rovno amber (35 Ma), with the description of two new species: Corethrella sontagae sp.n. based on a single male, and Corethrella rovnoensis sp.n. based on a single female. A revised key to fossil species of Corethrella is given. Phylogenetic relationships within Corethrella are investigated based on Bayesian and parsimony analysis, including the new data. All species groups recognized by Borkent (2008) are recovered as monophyletic, with the exception of the drakensbergensis group, which is found to be a paraphyletic grade. Both of the newly described species can be accommodated within modern species groups: C. sontagae shows affinities with the quadrivittata group and C. rovnoensis with the rotunda group.

Preferences for anuran calls in hematophagous corethrellids (Diptera: Corethrellidae) from Southern Brazil

et al. 2018

Corethrellids are hematophagous flies that locate their frog hosts by using their calls as an auditory cue. The attractiveness of frog calls to these insects has been associated with the complexity of the vocalisation or an evolutionary relationship between the fly and frog species. We investigated the possible preferences of a local Corethrella fauna for the calls of six anurans, three species of the genus Boana (Hylidae) and three Physalaemus (Leptodactylidae) species in the Atlantic Rainforest of southern Brazil. We recorded loops of the natural advertisement calls of the different frog host species, which we broadcast from acoustic traps consisting of modified CDC (Center for Disease Control) traps fitted with a speaker under the collecting system, but without a source of light. Nine species of hematophagous flies were captured during 360 h of trapping. Three of the species captured were new to Brazil, and two could not be identified and may represent new taxa. Two corethrellid species contributed 75% of the individuals captured and were present in all the acoustic traps, while three species were attracted to only one trap. The median richness and abundance of corethrellids varied significantly in relation to the different calls broadcast by the traps. These differences in the abundance and species richness of Corethrella in the traps indicate that the frog calls vary in their attractiveness to the hematophagous flies. A model-based analysis using mvabund also indicated that the frog species and genera that produced the calls used in an acoustic trap were a significant factor determining the composition of the Corethrella assemblages captured in that trap. The variation found in the Corethrella communities of southern Brazil may be explained not only by the acoustic traits of frog vocalisations but also by differences in the morphological and ecological characteristics of the frog species.
