Family Syrphidae – Syrphid Flies
Subfamily Syrphinae
Tribe Syrphini
Genus Ocyptamus

These types of syrphids are also referred to as hover flies or flower flies.

CENTRAL FLORIDA CRITTER OF THE DAY: Black Scavenger Fly (Family Sepsidae)

New to my buggy life list.  Well, not exactly new but the first clear photo I’ve gotten of this miniscule decomposer so I could identify what type of fly it was.

“Larvae live in excrement and various types of decaying matter. Adults found near material that the larvae feed on” (source: https://bugguide.net/node/view/8677)

These adults seem interested in areas where carcasses of aphids were left behind from molting and/or brachinid wasps, ladybug and syrphid fly larvae activity.

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.

CENTRAL FLORIDA CRITTER OF THE DAY: Robberfly ( Lampria bicolor)

New to my buggy life list.  Pretty excited since this seems to be an unusual find in Florida.
I am basing that on the fact that I-naturalist doesn’t have any documented sightings in the state. https://www.inaturalist.org/taxa/61573-Lampria-bicolor

Order Diptera – Flies
No Taxon Orthorrhapha
Superfamily Asiloidea

CENTRAL FLORIDA CRITTER OF THE DAY: Horse Fly (Tabanus sp. possibly fuscopunctatus)

New to my buggy life list.  This VERY LARGE! female attracted my attention when she flew by me and landed on the front of my car in the driveway.
Feeds on mammals. Not particularly inclined to bite humans, but should you get bit you will know it. More a pest of livestock.

CENTRAL FLORIDA CRITTER OF THE DAY: Green Hover Fly (Ornidia obesa)

New to my buggy life list.  Some resources state that the larvae develop in semi-liquid waste including latrines, and the following website shows egg laying on vegetation directly above a compost area.

http://www.backyardnature.net/yucatan/greenfly.htm

Family Syrphidae (Syrphid Flies)
Subfamily Eristalinae
Tribe Volucellini

Other common names: flower fly

There are indications that they may carry bacteria, but also be beneficial in converting coffee waste into cattle feed.  Mixed bag of beneficial/scary in my book.

Another view….and it did thwart the tiny spider from grabbing hold.

CENTRAL FLORIDA CRITTER OF THE DAY: Secondary Screwworm Fly (Cochliomyia macellaria)

One of the Blow Flies (Calliphoridae Family)

May present a problem with livestock that have untreated wounds:  “…this species does not feed on actual living tissue as does the primary screwworm. Secondary screwworms invade to feed on dead tissues…”

” The secondary screwworm is considered to be very beneficial as a decomposer.”

“…this species has gained recognition in the field of forensic entomology as a principal species on which to base postmortem interval estimations…”

synonym Mallophora nigra (https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=133770#null)

Bee Mimic; diptera; predatory.  The larval stage of this insect’s lifecycle lives in the soil and are predatory on some pest soil dwellers such has grubs.

Although robber flies are predators, they are sometimes prey for other animals, including spiders, birds, and larger predatory insects like assassin bugs, praying mantids, and even other robber flies. Moles and underground arthropod predators, such as centipedes and ground beetle larvae sometimes eat them. (source: http://www.uky.edu/Ag/CritterFiles/casefile/insects/flies/robber/robber.htm)
