Other fun facts:

  • You can tell males from females because males have a pair of curved horns on their head; whereas females are hornless. This difference between sexes is called “sexual dimorphism.”
  • Bull-headed dung beetles have been introduced to different areas to control sheep and cattle manure.
  • This species of beetle is only 0.5 to 1 cm long.
  • Scientific name: Onthophagus taurus
  • Extreme fact: The bull-headed dung beetle is able to lift 1,141 times its weight. It is the strongest animal based on a weight to lift ratio.
  • Comparison: Its strength is similar to a human pulling 6 buses. Humans can typically lift 1 to 1.3 times their bodyweight.
  • Present in VA: Yes
  • Range: Widespread (Australia, the Middle East, Central Asia, United States, and Europe)
  • Habitat: Grasslands and savannas
  • Diet: Dung generalist (meaning it eats the poop of a wide variety of animals)
  • Predators: Birds, lizards, small mammals, scorpions, spiders, beetles, and vinegaroons

Other fun facts:

  • The caterpillar (or juvenile form) of this moth is currently unknown.

Other fun facts:

  • The Mediterranean supercolony along with a California supercolony and a Japanese supercolony are thought to form a disconnected global “mega-colony” from the same genetic stock.
  • Argentine ants are vectors of viral diseases that can infect bees and other ant species. One virus causes bees to develop deformed wings.

  • Comparison: Population of countries the supercolony is present in:
    • Spain: 47 million people
    • Portugal: 10 million people
    • France: 67 million people
    • Italy: 60 million people
    • Total: 184 million people
  • Present in VA: No
  • Range: Largest supercolony
  • Habitat: Grasslands, wetlands, human distrubed areas
  • Diet: Arthropods, small amphibians, small reptiles, honeydew, and fruits
  • Predators: Various beetles, flies, lizards, frogs, salamanders, spiders, parasitic wasps, nematodes, mammals, and birds

Meadow Spittlebug

Other fun facts:

  • Meadow spittlebugs are 7 mm long.
  • Immatures, also known as nymphs, form a foam cover to protect themselves from predators, hence the name spittlebug.
  • Also known as the Meadow Froghopper, Common Spittlebug, Common Froghopper, and Cuckoo-spit Insect.
  • Scientific name: Philaenus spumarius
  • Extreme fact: The meadow spittlebug can jump 2 feet in the air, which is 87 times its body length.
  • Comparisons: This is similar to a 5 ½-foot person jumping 478 feet or 44 stories high. The South African sharp-nosed frog can jump about 11 feet - 6 to 8.5 times higher than spittlebug.
  • Present in VA: Yes, but it is invasive
  • Range: North America, Europe, North Africa, and Northern Asia
  • Habitat: Meadows and grasslands
  • Diet: Plant sap
  • Predators: Birds, spiders, ants, wasps, beetles, and flies

  • Scientific name: Xanthopan morganii
  • Extreme fact: The Morgan’s sphinx moth has a proboscis that is 1 foot in length. A proboscis is a long, straw-like mouthpart that some insects use to drink fluids.
  • Comparisons: This would be like a 5-foot-tall person with a 20-foot-long tongue! Giant anteaters are 6-7 feet long and have an approximately 2-foot-long tongue, which is the longest vertebrate tongue.
  • Present in VA: No
  • Range: Southern Africa
  • Diet: Caterpillars (the juvenile form of the Morgan's sphinx moth) feed on plant leaves in the Soursop family. Moths (the adult form) feed on flower nectar.
  • Predators: Birds, frogs, lizards, spiders, small mammals

Other fun facts:

  • The Morgan’s sphinx moth has a 6-inch wingspan and approximately 3-inch-long body.
  • It is the sole pollinator of the Madagascar orchid.
  • The long proboscis is a result of coevolution with the Madagascar orchid, which has a foot-long nectary.
  • A subspecies of the moth, Xanthopan morganii praedicta, was named for Alfred Russel Wallace predicting that there would be an insect with a foot-long proboscis to match the foot-long nectary of the Madagascar orchid.


Driver Ant

  • Males get the name "sausage fly" for their round elongate appearance.
  • Each colony can have around 20 million individuals.
  • Driver ants are mostly nomadic, only forming temporary anthills.
  • East Africa tribes will use the soldier ants as surgical staples due to their great bite force.
  • Scientific name: Dorylus wilverthi

Other fun facts:

  • Unlike ants, fungus-growing termites have a king that continuously mates with the queen.
  • The mounds are specially designed to maintain temperatures through specialized ventilation.
  • Termites are actually a group of cockroaches that live in large colonies, similar to how ants are ground dwelling wasps that live in large colonies.
