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

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.

CENTRAL FLORIDA CRITTER OF THE DAY: Dark Flower Scarab Beetle (Euphoria sepulcralis)

These beetles are pollinators although this one was chowing down on my blackberries.

“The adults feed on tree sap, a wide variety of ripening fruits, corn, and the flowers of apple, thistle, mock orange, milkweed, dogwood, sumac, yarrow, daisies, and goldenrod.” Ratcliffe (1991)

CENTRAL FLORIDA CRITTER OF THE DAY: Darkling Beetle (Bothrotes canaliculatus acutus)

new to my buggy life list.  Darkling Beetles, as scavengers, are usually found in dark locations such as under debris, logs or stones.  This guy must have been “slumming”. They are members of the Tenebrionidae Family.

I arrived at the subspecies given the metallic luster based on this key: http://entnemdept.ufl.edu/teneb/subfamily_Pimeliinae.pdf

A study indicated the genus may feed on moth larvae:

“Species found preying on Mocis larvae were a Tenebrionid, Bothrotes fortis…”

CENTRAL FLORIDA CRITTER OF THE DAY: BLISTER BEETLE (Nemognatha nemorensis) mating

adults feed on flowerparts of Asteraceae (Rudbeckia, Bidens, Erigeron, Heterotheca, Eupatorium spp.)
larvae feed on eggs, larvae, and food reserves of ground-nesting bees

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.
