Flower Longhorn Beetle (Xestoleptura crassicornis): While we’re pretty confident we’ve positively identified this species of longhorn beetle, little information exists on their habits. There are over 25,000 species of longhorn beetles worldwide. They are aptly named (with antennae often as long as or longer than their body) and are often colorful (iridescent green, black and yellow, black and red, etc.).
