CENTRAL FLORIDA CRITTER OF THE DAY: Air Potato Leaf Beetle (Lilioceris cheni)

THEY’RE BACK! First I’ve seen in 2017. I just emailed the coordinates to the USDA as requested in the information sheet from UF Entomology.

Introduced as biocontrol for the highly invasive Air potato vine (Dioscorea bulbifera). Feeds exclusively on this non-native species of plant.

I’m not aware of any air potato in the area so I guess they are just fueling up on nectar while they seek out the host for their larvae.

If you have air potato vines in your area, you can apply to receive beetles for release: http://bcrcl.ifas.ufl.edu/airpotatofiles/airpotatoforms.shtml

It was sharing real estate with a paper wasp:

CENTRAL FLORIDA CRITTER OF THE DAY: Spotless Lady Beetle (Cycloneda sanguinea) larva

This species of ladybug is native to Florida.
Diet: aphids. The larval stage is perhaps more beneficial than as adults since larvae have voracious appetities. If you wash your aphids off your ornamental plants, you remove the food source for the beneficial so they will go elsewhere to reproduce. Be patient and let nature take care of itself.
