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

THEY’RE BACK! First I’ve seen in 2016. 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.

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

This species of ladybug is native to Florida.
Diet: aphids. The larval stage may be even more beneficial than as adults since the 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.

Keep in mind that Not all ladybugs without spots are native. Harmonia is an introduced species which can outcompete our natives, especially the species in the photo. (source: https://esa.confex.com/esa/2001/techprogram/paper_1422.htm)

If you buy ladybugs, check what species you are introducing. Many sold commercially are non-native species.

The balance hatch. You can see that there are already exoskeletons from aphids. If there were no aphids these guys would starve

My take: There are Different Types of Ladybugs? (includes side by side photos to tell the exotic from our native species)

As the larva grows it moves on to bigger bounty such as the cocoon of a leaf eating goldenrod beetle.
