Water Hyacinth Weevil - Neochetina eichhorniae ? - Neochetina eichhorniae Middleburg, Clay County, Florida, USA July 30, 2009 Size: 4.66mm
Collected at light. This keys out using Am. Beetles Vol II as Neochetina. Of the 2 species
in FL, N. bruchi and N. eichhorniae, N. bruchi has an obvious chevron on the dorsum, but
the size here fits the female for that species. On the other hand, there is a comparative
photo on BG for N. eichhorniae which shows the same characteristics as this one has. The
biggest problem is the size. Dr O'brien's 1976 paper on the species, and another web site
show males @~3.2mm and females @~3.7mm, where this specimen is ~ 1mm larger. Still going
with my guess so any comments most welcome
