Vegreville egg
The Vegreville egg is a giant sculpture of a pysanka, a Ukrainian-style Easter egg. The work by Paul Maxum Sembaliuk is built of an intricate set of two-dimensional anodized aluminum tiles in the shape of congruent equilateral triangles and star-shaped hexagons, fashioned over an aluminum framework. The egg is long and three and a half stories high, weighing in at . It is the second largest pysanka in the world. The biggest one was built in Kolomyia, Ukraine in 2000.
Dinoponera
"Dinoponera" contains one of the largest species of ants in the world, with female "Dinoponera gigantea" specimens measuring in length. Size is the most obvious character distinguishing "Dinoponera" from other genera. The only other ants with a worker caste approaching this size are "Paraponera clavata" (the bullet ant) and the larger "Pachycondyla" such as "P. crassinoda", "P. impressa" and "P. villosa". "Paraponera clavata" is easily separated by its anvil-shaped petiole with a spine on the ventral surface, highly sculptured body and deep antennal scrobes. "Pachycondyla" is regarded as the sister taxa to "Dinoponera". "Dinoponera", in addition to their size, are distinguishable from "Pachycondyla" by the presence of two laterally projecting clypeal teeth and rows of spines on the pygidium and hypopygidium.
