I have looked at all the black and white beetles and cannot find one that looks quite like this. It was on dog fennel in west central Florida. I would like to know what it is and if it is native. It looks like it is missing an antennae.
Thank you for this wonderful reference site.

This looks to us like a Diaprepes Root Weevil, Diaprepes abbreviatus, a species that according to BugGuide is: “Native to the Caribbean, adventive and established in so. US: so. & central FL (1964), so. TX (Cameron & Hidalgo Cos 2000, Corpus Christi 2005, Houston 2009; map), so. CA (2005), LA (2008); further north in greenhouses.” BugGuide also indicates it is “highly polyphagous; larvae feed on roots, adults on foliage of citrus trees (esp. oranges in TX) and almost 300 other plant species” and “Major pest of citrus crops: larvae often girdle the taproot, which may kill the plant and provide an avenue for Phythophora infections. A single larva can kill young hosts while several larvae can cause serious decline of older, established hosts.”
