CENTRAL FLORIDA CRITTER OF THE DAY:  Sharpshooter (Phera insolita)

Phera insolita

New to my buggy life list, it flew and landed low on a blade of grass.  They suck fluids out of plants and also can be vectors for virus.

syn. Homalodisca insolita

“natural enemies of sharpshooters include predatory insects such as mantids and dragonflies. Free living and snare-building spiders also capture and eat sharpshooters. In Florida, anoles have been observed eating sharpshooters. Small parasitic wasps in the genus Gonatocerus”

CENTRAL FLORIDA CRITTER OF THE DAY: Bird Grasshopper Nymph (Schistocerca sp.)

DONT THINK PEST, THINK BIRD FOOD! Nymphs of grasshoppers are an important food source for birds especially fledglings who cannot eat seed.

If you maintain a balanced garden and dont use pesticides which can kill the beneficial insects, damage should be minimal to ornamentals.

Tachinid flies (Tachinidae family) are parasites of grasshoppers

Predators: Birds, lizards,mantids, spiders, and rodents eat grasshoppers. (source: http://web.archive.org/web/20150920015140/http://insected.arizona.edu:80/ghopperinfo.htm

Positive Impact on the Ecosystem:
As herbivores, grasshoppers link plants to the rest of the ecosystem. Frass (droppings) contribute to nutrient turnover by returning nutrients as fertilizer for the plants. They provide food for birds and other arthropods. (ibid.)

CENTRAL FLORIDA CRITTER OF THE DAY: Flesh Fly (subfamily Sarcophaginae)

Part of nature’s cleanup crew. Since it is feeding on a dead caterpillar this may be Sarcophaga sp.

“The majority of species within the large genus Sarcophaga may be scavengers of small carrion like dead insects and snails as well as smaller vertebrates, and only few species are breeding in larger vertebrate carcases and feces. ” source: http://www.zmuc.dk/entoweb/sarcoweb/sarcweb/biology/Srcphgna/Bio_Sarc.htm

CENTRAL FLORIDA CRITTER OF THE DAY: Syrphid fly Larvae Possibly Ocyptamus sp.

New type to add to my buggy life list.

BENEFICIAL. Can easily be mistaken for caterpillars. In the larval stage they eat soft bodied arthropods such as aphids (shown). As flying adults they are important pollinators.

“When larval populations are high, syrphid flies may kill 70 to 100% of an aphid population.” source: https://ipm.ifas.ufl.edu/pdfs/SyrphidFly.pdf

Identification possibility based on photos of similar larva found via search engine

I am ruling out Ocyptamus fuscipennis which I previously documented in the larval stage: https://floridawildlifegardentails.wordpress.com/2015/08/05/aphids-are-good-wait-what/

It may be Ocyptamus cylindricus species group since I’ve documented adults of that species on Bidens in the past. https://floridawildlifegardentails.wordpress.com/2017/09/01/war-on-aphids/

CENTRAL FLORIDA CRITTER OF THE DAY: Yellow-Striped Armyworm Moth Caterpillar (Spodoptera ornithogalli)

Generalist who eat multiple crops so not a favorite with farmers. There are many native hosts and they are parasitize by wasps and tachinid fly which are needed pollinators. Also preyed upon by the likes of damsel, big-eyed and pirate bugs making these moths have an important roll in the circle of life.

Larval host: include but are not limited to Florida native Rumex sp., Lactuca sp. and Plantago sp.

CENTRAL FLORIDA CRITTER OF THE DAY: Spined Assassin Bug (Sinea sp. possibly diadema) nymph

Predaceous on pest insects such as this Skeletonizing Leaf Beetle larva (Ophraella sp.)
