Wasps

CENTRAL FLORIDA CRITTER OF THE DAY: Tiphiid Wasp (Tiphia sp.)

Parasitoids of White Grubs (larva of japanese beetles)  This guy (gal?) was enjoying the honeydew produced by aphids on the wild lime tree.

“Tiphia wasps’ presence is greatly influenced by the availability of adult food sources. The female adults feed in the morning in vegetations for food, such as nectar or honeydews (emitted by aphids or whiteflies), before looking for grubs to deposit their eggs. Under favorable conditions they can parasitize up to 60% of beetle larvae in a given area. Like other insects, they are killed by pesticide, so it is not advised to use pesticides indiscriminately (Ohio State University, 2003).”

“Two species of tiphiid wasps, Tiphia vernalis Rohwer and Tiphia popilliavora Rohwer have proven successful biocontrol agents against Japanese beetle grubs (Fleming 1976). Tiphia vernalis attacks overwintering grubs, whereas Tiphia popilliavora attacks young grubs in late summer.” source: https://edis.ifas.ufl.edu/in630

CENTRAL FLORIDA CRITTER OF THE DAY: Chalcid Wasp (Conura sp.)

Parasitic.

Family Chalcididae – Chalcidid Wasps
Subfamily Chalcidinae

Primary hosts are beetles and flies, but it also uses butterflies and moths.  Click here for list of known prey, predators and plant associates

Shown on Florida Native Plant: Bidens alba

CENTRAL FLORIDA CRITTER OF THE DAY: Red-marked Pachodynerus Mason Wasp (Pachodynerus erynnis) with prey

a.k.a. Red and Black Mason Wasp

Use caterpillars as larval hosts including many pest species. If you look closely, this one dug some tiny bounty out of the bud.

CENTRAL FLORIDA CRITTER OF THE DAY:  Caribbean Scoliid Wasp (Dielis dorsata)

New to my buggy life list.

syn. Campsomeris dorsata

Superfamily Scolioidea
Family Scoliidae – Scoliid Wasps
Subfamily Campsomerinae

Introduced to Florida. ” to aid in reducing coleopteran pests in sugar cane agricultural systems. … and might still be an important biological control agent of white grubs in sugar cane as well as turf production and maintenance.”

CENTRAL FLORIDA CRITTER OF THE DAY: Thynnid Wasp (probably Myzinum carolinianum)

Beneficial

Larvae are parasitoids of white grubs so can be used in biological control.

Adults pollinate

Order Hymenoptera – Ants, Bees, Wasps and Sawflies
No Taxon Aculeata – Ants, Bees and Stinging Wasps
Superfamily Thynnoidea
Family Thynnidae – Thynnid Wasps
Subfamily Myzininae
Genus Myzinum

CENTRAL FLORIDA CRITTER OF THE DAY: Potter/Mason Wasp (Euodynerus sp. likely castigatus rubrivestis)

New to my buggy life list.   I initially thought this was a Red-marked Pachodynerus Mason Wasp (Pachodynerus erynnis) but it seemed too small.  On closer examination I saw the red dots on the rear, side and behind the eye which led me to this species.

Eumenines prey mainly upon moth larvae, although some take larvae of leaf-feeding beetles. Adults take nectar.
Superfamily Vespoidea – Yellowjackets and Hornets, Paper Wasps; Potter, Mason and Pollen Wasps and allies
Family Vespidae – Yellowjackets and Hornets, Paper Wasps; Potter, Mason and Pollen Wasps
Subfamily Eumeninae – Potter and Mason Wasps
Genus Euodynerus

There are many different species in this genus found in the state of Florida.  See the collection list here:  https://www.freshfromflorida.com/Divisions-Offices/Plant-Industry/Florida-State-Collection-of-Arthropods/Explore-the-Collection/Insect-Collection/Hymenoptera2/Vespidae

There is interesting documentation on the subspecies of certain wasps in Florida that appear to have taken on red coloration where it is yellow in other locations.  Research paper:

“Lists are presented of 79 species of Florida insects, mostly wasps, that have distinctive dark red markings on a black background. Most of these species have more northern relatives (subspecies or congeners) whose markings are yellow rather than red. This apparent replacement of yellow-marked forms by red-marked forms in Florida has occurred at least 31 times in different lineages. Yellow-marked and red-marked species may be sympatric in Florida. Biogeographic details of the phenomenon are poorly known.” Deyrup, Mark. (2009). Red and black coloration in Florida hymenoptera. Southeastern Naturalist. 2. 511-522. 10.1656/1528-7092(2003)002[0511:RABCIF]2.0.CO;2.
