Folks get ready for a snorkel near Cano Island in Costa Rica. See other beautiful phenomena from Costa Rica.

Symbiotic relationships are incredibly necessary neotropical ecosystems where many different species are spread out over large areas. Because of the multitude of species that can be found in a small area (compared to more temperate areas) it is evident that these species must have learned to coexist. The wasps of CR serve as good examples of these symbiotic organisms. Also, the wasp, at least for most people, has been stigmatized as a vicious, stinging pest. I hope to dispel this notion by opening eyes to the complex and interesting lifecycle biology of this group of insects.

OUTLINE

I. Intro to the Hymenoptera of Costa Rica and Central America
- What is included in hymenoptera?
- Narrowing of focus onto wasps
- Specific was species in CR (Sphecidae, Ichneumonidae) Social vs.
Solitary
- Touch on the importance of cataloging the biodiversity, especially in
insects
II. Wasps 1
- Focus on Sphecidae and Chalcid wasps
- Background info
- Biology and lifecycle of
- Symbiotic relationships they have with the surrounding ecosystems (fig
trees)
III. Wasps 2
- Focus on Ichneumonidae
- Background info
- Biology and lifecycle of
- Symbiotic relationships
IV. Biochemistry of Wasps and other Hymenoptera of CR
- uses in communication
- uses in defenses
- possible exploitation by humans for medicinal purposes
- prevention of human attacks?
V. Conclusion
- future of CR wasps
- future of efforts to record and document the biodiversity of the tropics
- use of the wasp as a model organism to represent many of the other symbiotic relationships that are vital to the lifecycle of many tropical species
