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: Tachinid fly (Gonia crassicornis)

Beneficial: Parasitic Fly. controls pest caterpillars of cash crops (think armyworm!) which they use as food for their developing larva.  The larvae of this one apparently also feed on May beetles. (source: https://bugguide.net/node/view/1041335)

CENTRAL FLORIDA CRITTER OF THE DAY: Syrphid Fly (Dioprosopa clavata)

Synonyms Pseudodoros clavatus

This beneficial pollinator uses aphids as a larval host and this one was laying eggs on southern beeblossom before settling in on the frogfruit for a drink.

Also called hover flies or flower flies.
