Dicromantispa sayi is a species of mantidfly in the family Mantispidae. It is found in the Caribbean Sea, Central America, and North America. [1] [2] [3]
Head: Brown to black with pale yellow marks. Face has a longitudinal yellow stripe each side of center; middle dark area appearing as a dark stripe, sometimes incomplete. Pattern of yellow oblong spots on top of head; can be obscure. Eyes multi-colored.
Antenna: Brown except segment 1 yellowish, more so on underside.
Thorax: Neck (prothorax) long and slender, more cone-shaped at head. Cream-colored patch at base and end of neck; rest yellowish-brown to dark brown. Usually with a light or dark colored longitudinal stripe down center. Thorax side on female dark with cream, curved lines. Male sides mostly pale.
Wings: Wings clear with brown veins; no brown spots at wing tips. Base and outside edge of wings dark brown (costa area), with a faint yellowish streak. Stigma at end of costa also dark brown.
Legs: Front legs modified, similar to praying mantis; dark brown with light streaks. Usually folded up and not used, except for eating. Mid and hind legs pale yellow with brown streaks; females have joint to body (coxae) brown; male coxae pale.
Abdomen: Yellowish-brown to dark brown with yellow marks. Female abdomen always darker, and may be entirely black; the yellow marks vary considerably. Abdomen side edges cream, almost entirely on male, more spotted on female.
Similar Species: Dicromantispa interrupta is a larger species with a dark patch near tip of wing.
Leptomantispa pulchella has side-by-side (paired) yellow stripes of even width running down sides of abdomen, whereas D. sayi has uneven width pattern down sides.
L. pulchella also has a bright, burnt orange stigma on wings, not brown as in D. sayi. Otherwise, these two are identical.
Size: 14 to 15 mm long.
Habitat: Forest edges and prairies where spiders are present.
Food: Adults feed on small flying insects. Larvae hunt for just about any species spider eggs, but major hosts are Wolf and Hunting spiders Lycosidae, and Running Crab Spider Philodromus vulgaris .
Flight Time: Jul 15 to Sep 4th. Peaks end of July
Life Cycle: Females lay eggs on any substrate. Larvae hatch, wander, find and either penetrate wolf spider egg sacs, or hitch a ride on adult female spiders ready to lay eggs. 1st instar over-winters. One generation per year.

Apatura iris, the purple emperor, is a Palearctic butterfly of the family Nymphalidae.
The small mountain ringlet or mountain ringlet is a butterfly of the family Nymphalidae. It is found in mountainous regions of southern and central Europe.
The common darter is a dragonfly of the family Libellulidae native to Eurasia. It is one of the most common dragonflies in Europe, occurring in a wide variety of water bodies, though with a preference for breeding in still water such as ponds and lakes. In the south of its range adults are on the wing all year round.
The cabbage moth is primarily known as a pest that is responsible for severe crop damage of a wide variety of plant species. The common name, cabbage moth, is a misnomer as the species feeds on many fruits, vegetables, and crops in the genus Brassica. Other notable host plants include tobacco, sunflower, and tomato, making this pest species particularly economically damaging.
Mantispidae, known commonly as mantidflies, mantispids, mantid lacewings, mantisflies or mantis-flies, is a family of small to moderate-sized insects in the order Neuroptera. There are many genera with around 400 species worldwide, especially in the tropics and subtropics. Only five species of Mantispa occur in Europe. As their names suggest, members of the group possess raptorial forelimbs similar to those of the praying mantis, a case of convergent evolution.
Micrommata virescens, common name green huntsman spider, is a species of huntsman spiders belonging to the family Sparassidae.
The scarce copper is a butterfly of the family Lycaenidae.
Spilomyia sayi, the Four-lined Hornet Fly, is a fairly common species of syrphid fly. This species is found from western Canada to northeastern North America. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are known as the short-tailed larvae, suited for moist areas such as rot holes of trees. It is a wasp mimic.
Trichopoda pennipes is a species of feather-legged fly in the dipteran family Tachinidae.
Beris chalybata, the murky-legged black legionnaire, is a European species of soldier fly.
Toxomerus politus, commonly known as the maize calligrapher, is a species of hoverfly. It is known from North, Central and South America. Although little is known about the early stages of this species, associations with corn have been noted. The adults and likely the larvae feed on the pollen of the corn plants.
Psorophora ciliata is a species of large mosquito indigenous to the United States east of the continental divide. It is one of thirteen species of the genus that reside in the continental United States. The mosquito has been referred to as the “gallinipper” or “shaggy-legged gallinipper” due to its tendency for aggressive behavior.
The long-legged marsh glider or dancing dropwing is a species of dragonfly found in Asia.
Climaciella brunnea, known sometimes by the common names wasp mantidfly, western mantidfly, and brown mantidfly, is a predatory neuropteran insect in the family Mantispidae.
Sinolestes is a genus of damselfly in the family Synlestidae. It is monotypic, the sole species being Sinolestes editus. It is found in southeastern China, Taiwan, and probably northern Vietnam.
Brachyopa flavescens, The Yellow Sapeater, is a fairly common species of syrphid fly. It has been observed in northeastern North America. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae for this genus are of the rat-tailed type. B.flavescens larvae have not been described.
Diminutella is a genus of spiders in the family Sparassidae. It was first described in 2018 by Rheims and Alayón. It is a monotypic genus with one described species, Diminutella cortina. It is endemic to Pinar del Rio, Cuba.
Orthonevra pictipennis (Loew,1863), the Dusky-veined Mucksucker, is an uncommon species of syrphid fly. It has been observed in North America. O. pictipennis shares much of the same range as O. pulchella, O. nitida and O. feei. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies, for they are commonly found around and on flowers from which they get both energy-giving nectar and protein-rich pollen. Larvae for this genus are of the rat-tailed type. O. pictipennis larvae have not been described.
Dicromantispa interrupta is a species of mantidfly in the family Mantispidae. It is found in Central America and North America. Larvae develop in the egg sacs of hunting spiders. Adults have spotted wings.
Sphiximorpha willistoni, or Williston's wasp fly, is a rare species of syrphid fly found in eastern North America. It is a strong wasp mimic. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae in this genus are found in sap runs of trees.
