  • This facility contains two collections of the Division of

  • Invertebrate Zoology.

  • Both part of the hymenoptera, the ants, bees and wasps.

  • One collection, housed in these half-height cabinets down this corridor,

  • is the wasp nest collection, which is the worlds largest.

  • The other collection, housed in these cabinets,

  • is the gall wasp collection of Alfred Kinsey, who studied gall wasps well

  • before he started studying human sexuality. Social wasps are very familiar

  • to people

  • and have been

  • since time immemorial.

  • Possibly humans got the idea for making paper from watching wasps chew wood

  • and mixing it with saliva. This is a complicated beautiful structure,

  • and it's made by a group of insects that have a brain about the size

  • of a pin head.

  • Now, to make something that complex, all of these insects have to have a complex

  • society. And the nests are indicators of that. In the American

  • tropics these wasps are subject to predation by birds, monkeys and so

  • they've evolved

  • visual camouflage. Other examples of disguise include this nest which was

  • taken from the side of a tree. Each of these are separate cones and

  • they're built on an envelope, the envelope of the preceding cone, so it's like

  • they're stories that are stacked. They can build one of these large nests

  • within two days, and that's because the nests are made by swarms of queens

  • accompanied by swarms of workers.

  • We have Kinsey's collection

  • because he grew up in South Orange, New Jersey, across the river, and got his

  • first entomological instruction

  • here at the American Museum, so when he died his collection was willed to us.

  • In addition to the the wasps, Kinsey collected many galls. We have a

  • collection now of more than seven

  • millions specimens. A gall is a structure made out of plant tissue.

  • The wasp comes along, lays an egg into the plant and the chemicals that

  • she injects when she's laying the egg

  • cause the plant to swell around it and produce these large growths that

  • the gall wasp larvae when it hatches starts to feed on.

  • If you're dealing with large numbers of very small objects, and you are

  • interested in the study of variation, you have to look at

  • a great many specimens.

  • And that's one reason that invertebrate zoology

  • has so many specimens. In fact,

  • entomology has the majority of the objects in the entire Museum's

  • collection,

  • about eighteen million

  • specimens are part of entomology.
