Other types of insect in this #chalkstream ditch included #hemiptera, two sorts of water boatmen, perhaps red eyed Hesperocorixa by the Water Violet & Vermicorixa & a Milky Backswimmer (Notonecta) plus some natty little Deronectina predaceous diving beetles. #invertefest #norfolk #Corixidae 12/14

New paper out with @vane_cespe in @BioInvasions Eco-immunology of native and invasive water bugs #corixidae in response to water mite ectoparasitism, with field and experimental data #immunity #parasite @ebdonana #invasivespecies #Trichocorixa
Water mites #hydrachnidia are important #ectoparasites in #doñana. One larva stops #corixidae nymphs from reaching adulthood, or greatly reduces adult fecundity, #Corixa #Sigara @ebdonana
Life cycle of one of Europe's few alien aquatic insects, the waterboatman #Trichocorixa #Corixidae, in saline Iberian #wetlands. Winter reproduction and high fecundity allow it to outcompete native taxa #Sigara #EBDpub #invasivespecies @ebdonana @IEA_UdG
American #Corixidae waterboatmen #Trichocorixa verticalis are taking over in coastal Iberia. In saline sites (left) they have excluded natives such as #Sigara selecta. In fresh sites (right) they coexist mainly with S. lateralis. #invasivespecies @ebdonana
