CENTRAL FLORIDA CRITTER OF THE DAY: Syrphid Fly (Toxomerus sp. likely boscii)

a.k.a. Hover fly, flower fly, hoverfly; Thin-lined Calligrapher

This bee mimic is BENEFICIAL in both adult and larval stages.

Re: identification: “The main characters are: the yellow stripe on the mesonotum is not very thick and the hind femur has a black ring.” source: https://bugguide.net/node/view/351203

CENTRAL FLORIDA CRITTER OF THE DAY:  Hairy Maggot Blow Fly (Chrysomya sp.)

Calliphoridae Family (blowflies).  Introduced.  Potential to cause disease in livestock.  Larval Stage provides significant benefits in Forensic Medicine

larvae feed on carrion
Adults pollinate

CENTRAL FLORIDA CRITTER OF THE DAY: Tachinid fly (Archytas sp.)

Beneficial: Parasitic Fly. control of pest caterpillar (think armyworm and cutworm!) which they use as food for their developing larva.

Performs some pollination as adults take nectar.

Tachinids are parasitoids of other insects, but the most common hosts are caterpillars.
Owlet Moths (Noctuidae) » Cutworm or Dart Moths (Noctuinae) and armyworms are known hosts per Taxonomic and Host Catalogue of the Tachinidae of America North of Mexico

CENTRAL FLORIDA CRITTER OF THE DAY: Syrphid Fly (Palpada sp. likely agrorum)

New species for me.  This one is considerably smaller than others I have seen in the genus.

They are Bee mimics.  Other common names: hover fly; flower fly

As a member of the Tribe Eristalini  the larvae live in organic rich water.

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

New to my buggy life list.

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…”

CENTRAL FLORIDA CRITTER OF THE DAY: Six-spotted Bromeliad Fly (Copestylum sexmaculatum)

New to my buggy life list.

One of the Syrphid Flies (Syrphidae Family)
Subfamily Eristalinae
Tribe Volucellini

Also known as Hover flies, flower flies or drone flies they pollinate. Some syrphid larva prey on aphids while this larvae of this genus feeds on “decaying matter, mostly rotting cactus (many spp. reared from Opuntia) (Marcos-García & Pérez-Bañón 2001)”.

CENTRAL FLORIDA CRITTER OF THE DAY: Longlegged Fly (Condylostylus mundus)

These members of diptera are very tiny but you can’t miss the bright blue iridescent color of this male.

Beneficial.  “Long-legged flies are predators and are therefore considered beneficial to have around for pest control. They have been known to feed on a rather wide variety of other small arthropods, including other flies, thrips, aphids, mites, springtails, leafhoppers, whiteflies, beetle larvae, and even termites!” (source: https://ohioline.osu.edu/factsheet/ent-69)

“The prey species are mostly Diptera, and more than half belong to the families Chironomidae and Culicidae [midges and mosquitoes]. However, various Condylostylus species (Diptera: Dolichopodidae) have been recorded to prey on dark-winged fungus gnats, leaf-miner flies, aphids, leafhoppers, thrips, whiteflies, and mites.” (source: http://www.bioone.org/doi/10.1653/024.100.0243)
