Duilia Setacci: An Extinct Genus of Spider Wasps

Duilia setacci is an extinct genus of spider wasps in the family Pompilidae. The genus contains only one species, Duilia ruffoi, which was described from a single fossil found in Baltic amber. The fossil is estimated to be around 34 million years old, making it one of the oldest known spider wasps.

Spider wasps are a diverse group of wasps that prey on spiders. They use their long, slender ovipositors to inject venom into their prey, paralyzing them. The wasps then lay their eggs on the paralyzed spiders, and the wasp larvae feed on the spiders as they develop.

Duilia setacci is a relatively small spider wasp, with a body length of around 10 mm. It has a black body with yellow markings on the face and legs. The wasp's wings are clear, with a dark brown band across the middle.

The discovery of Duilia setacci provides important insights into the evolution of spider wasps. The wasp's unique combination of characters suggests that it is a transitional form between the more primitive spider wasps and the more derived spider wasps that are found today.

Extinct genus

Duilia setacci is an extinct genus of spider wasps, meaning that it is a group of organisms that no longer exists. The only known species in this genus is Duilia ruffoi, which was described from a single fossil found in Baltic amber. This fossil is estimated to be around 34 million years old, making it one of the oldest known spider wasps.

Definition
An extinct genus is a genus that no longer exists. It is a taxonomic rank below family and above species.
Causes of extinction
Extinction can be caused by a variety of factors, including climate change, habitat loss, and competition from other species.
Importance of extinct genera
Extinct genera can provide important insights into the evolution of life on Earth. They can help us to understand how species have changed over time, and how ecosystems have responded to environmental changes.

Spider wasps

Duilia setacci is an extinct genus of spider wasps that lived around 34 million years ago. It is known from a single fossil found in Baltic amber. The wasp's unique combination of characters suggests that it is a transitional form between the more primitive spider wasps and the more derived spider wasps that are found today.

The discovery of Duilia setacci provides important insights into the evolution of spider wasps. It shows that spider wasps have been preying on spiders for millions of years, and that they have evolved a variety of adaptations to help them capture and subdue their prey.

Spider wasps are important predators of spiders. They help to control spider populations, and they can also be used as biological control agents for spiders that are considered pests.

Baltic amber

Baltic amber is a fossilized resin from extinct coniferous trees that lived around 34 million years ago. It is found in the Baltic Sea region, and it is known for its unique golden color and clarity. Baltic amber is often used in jewelry and other decorative objects.

Preservation of organisms
Baltic amber is a valuable source of information about the organisms that lived during the Eocene epoch. Many insects, plants, and other small organisms have been preserved in Baltic amber, providing scientists with a glimpse into the past.
Insights into ancient ecosystems
The organisms preserved in Baltic amber can help scientists to reconstruct the ecosystems that existed millions of years ago. For example, the presence of certain types of insects can indicate the presence of specific plants or flowers.
Evolutionary relationships
Baltic amber can also help scientists to understand the evolutionary relationships between different organisms. By comparing the organisms preserved in Baltic amber to their modern-day relatives, scientists can learn about how species have changed over time.
Climate change
Baltic amber can also provide information about past climate change. The types of plants and insects preserved in Baltic amber can indicate the climate conditions that existed at the time.

The discovery of Duilia setacci in Baltic amber is significant because it provides important insights into the evolution of spider wasps. The wasp's unique combination of characters suggests that it is a transitional form between the more primitive spider wasps and the more derived spider wasps that are found today.

34 million years old

The fossil of Duilia setacci is estimated to be around 34 million years old, making it one of the oldest known spider wasps. This fossil is significant because it provides important insights into the evolution of spider wasps.

The age of the fossil tells us that spider wasps have been preying on spiders for at least 34 million years. This is a significant amount of time, and it suggests that spider wasps have had a long and successful evolutionary history.

The age of the fossil also helps us to understand the evolutionary relationships between different spider wasps. Duilia setacci has a unique combination of characters that suggests that it is a transitional form between the more primitive spider wasps and the more derived spider wasps that are found today.

Unique combination of characters

Body size and shape
Duilia setacci is a relatively small spider wasp, with a body length of around 10 mm. It has a black body with yellow markings on the face and legs. The wasp's wings are clear, with a dark brown band across the middle.
Ovipositor
The ovipositor is a long, slender tube that female spider wasps use to inject venom into their prey. Duilia setacci has a relatively short ovipositor, which is not as specialized as the ovipositors of more derived spider wasps.
Legs
The legs of Duilia setacci are relatively short and stout, which is not as well-adapted for running as the legs of more derived spider wasps.
Wings
The wings of Duilia setacci are relatively short and broad, which is not as well-adapted for flying as the wings of more derived spider wasps.

The unique combination of characters in Duilia setacci suggests that it is a transitional form between the more primitive spider wasps and the more derived spider wasps that are found today. This wasp provides important insights into the evolution of spider wasps, and it helps us to understand how these wasps have changed over time.

Transitional form

Duilia setacci is a transitional form of spider wasp that lived around 34 million years ago. It is known from a single fossil found in Baltic amber. The wasp's unique combination of characters suggests that it is a transitional form between the more primitive spider wasps and the more derived spider wasps that are found today.

As a transitional form, Duilia setacci provides important insights into the evolution of spider wasps. It shows that spider wasps have been preying on spiders for at least 34 million years, and that they have evolved a variety of adaptations to help them capture and subdue their prey.

The discovery of Duilia setacci also highlights the importance of transitional forms in understanding the evolution of life on Earth. Transitional forms provide a link between different groups of organisms, and they can help us to understand how these groups have evolved over time.
