An invasive species of ant has been discovered in Europe for the first time. Nearly 90 nests of the red imported fire ant, or Solenopsis invicta, were found near the city of Syracuse, Italy, according to a new report published in the journal Current Biology. While the ants have occasionally been found in imported products in Europe, this is the first time they have become established in the wild.

The Texas Parks and Wildlife Department (TPWD) received a report in late June that an invasive silver carp had been spotted in Choctaw Creek, a Texas tributary of the Red River approximately 15 miles downstream from Lake Texoma. "These are the first reports of silver carp from Texas waters, although they have previously been found in other areas of the Red River including just downstream from Lake Texoma in Oklahoma waters in 2019," said Dan Bennett, TPWD fisheries management biologist. "Invasive carp pose a significant risk to Lake Texoma’s ecosystem and boaters and there is adequate flow and upstream river area for them to become established and reproduce in the lake if introduced."
Anyone who catches either silver carp or bighead carp in Texas waters is asked to report the sighting with location information and photos to AquaticInvasives@tpwd.texas.gov. Silver and bighead carp are prohibited exotic species in Texas and must be killed upon possession by beheading, gutting, gill-cutting or other means or placed on ice. Neither species can be possessed live.
