NATIONAL MUSEUM OF NATURAL HISTORY GEOTOUR
The Smithsonian’s National Museum of Natural History GeoTour will be discontinued at a date to be determined in the first quarter of 2018. The NMNH GeoTour was launched April 2, 2013; and we’ve appreciated the support and positive feedback on the NMNH GeoTour from the Geocaching community. We have enjoyed reading your logs. We hope; and I believe we did, through the cache pages and puzzles, provided a different look into the National Museum of Natural History. We wish it could continue but that will not be possible. We wanted to let you know, at this time, so that if you wish to do the tour it should not be put off. As of 4/20/2017 there remain 125 coins to be awarded for completing the tour.
The National Museum of Natural History GeoTour, launched on April 2, 2013, consists of nine caches in the District of Columbia, Maryland, Pennsylvania, and Virginia. Caches need not be accomplished in any particular order; each can be treated and logged as a stand-alone cache. Geocachers must download a passport, in which the code word(s) from each cache must be recorded. Each cache will take a greater time commitment than most caches due to the nature of the puzzles being a combination of web research and field puzzles. Some caches are in high traffic areas and will be extremely difficult to retrieve without drawing attention. Be prepared to explain what you are doing to lots of passersby. If you intend to do all the caches in one time, it will serve you well to read each cache page and determine the various locations that information for each of the final cache locations must be gathered. Information may have to be gathered from the web (cache-specific sites are listed on the appropriate cache page), in the museum, on the individual cache pages, and in state parks or forests. Each of the nine caches will feature a department but it will be seen that in nature, the subjects of these caches are not so easily pigeon-holed.
This cache features the Smithsonian Institution’s National Museum of Natural History’s Pollinator Garden, Department of Entomology, Butterfly Pavilion, and the Orkin Insect Zoo.
The butterfly is a flying flower,
The flower a tethered butterfly.
-Ponce Denis Écouchard Lebrun
Moths and butterflies are very closely related, though in general, moths are active at night while butterflies are active during the day. Most moths spin cocoons before the caterpillar changes into a pupa; while butterfly caterpillars change into chrysalis with no surrounding cocoon. A domesticated moth produces all the fiber that we humans spin into silk cloth. Butterflies are insects, and thus have three pairs of legs and two pairs of wings. We all love to watch as they gather nectar from a flower or dance in the air as they go to who knows where. They are one insect that makes everyone smile. We get butterflies in our stomachs when we are anxious, nervous, or excited. You can swim the butterfly. There is the butterfly effect, which implies that small changes will result in greatly different outcomes. How did butterflies get the name “butterfly”? If you go on line you will find many different answers to that question, at this point in time the correct answer may be known.
Butterflies and moths are in the Order Lepidoptera (lepido is Greek meaning “scale” and ptera is Greek for wing; but you already know this word from flying reptiles or Pterosaurs, don’t you?). Moths and butterflies were given this name because their wings are covered with scales. You have probably seen the residue that is left on your fingers after handling a moth or butterfly. These are the scales that were rubbed off the wings.
A butterfly is actually the final stage of a varied life; one that has 4 stages—egg, larva,pupa, and adult (butterfly)—each being completely different from the others. On your search for the final coordinates you will learn about the stages of a butterfly’s life. In the garden, depending the time of year, you may see any of the four stages. You will see, regardless of time of year, the last two stages inside the museum as you look for the cache's latitude. Most often, the first stage begins as an egg oviposited on a host plant. All the food necessary for the embryo to grow is contained inside the egg. The egg hatches and the larval stage begins. For butterflies, and the closely related moths, the larval form is more commonly known as a caterpillar. A caterpillar is an eating machine—a giant stomach with a mouth and legs. How many legs does a caterpillar have? They have 3 pairs of true jointed legs on its thorax. Behind on the abdomen, which is long and heavy, prolegs support the back of the caterpillar so it isn’t dragging its butt around. The prolegs are not jointed and are not true legs. The caterpillar’s job is to eat and eat, and as it eats, it grows and grows. During this short period of time, the caterpillar will shed its skin three or four times to make room for its growing body until it is finally ready to pupate and form the pupa.
“Well, I must endure the presence of a few caterpillars
if I wish to become acquainted with the butterflies.”
Antoine de Saint-Exupéry, The Little Prince
In the third, the pupal stage, most moth caterpillars spin a cocoon from silk glands located in their mouth and then form the pupa inside the protective cocoon. The butterfly caterpillar never spins a cocoon but form a chrysalis which is also the pupa. You will see chrysalides and cocoons when you are looking for “E” in the butterfly and moth emergence case. These chrysalides and cocoons remain here for a variable period of time. They can spend anywhere from 2 weeks to several months in this stage depending on the species or time of year, as some may enter into diapause during winter. During this time the caterpillar will metamorphose into the adult butterfly. In the Natural History Museum, there is a window in the Insect Zoo (free admission) into which you may look and see chrysalides hanging while the pupa undergo metamorphosis. These hanging chrysalides can be seen anytime the museum is open as this is the emergence case for the Butterfly Pavilion (fee to enter) in which the fourth and final stage of the butterfly’s life cycle can be seen (there is no data in the Butterfly Pavilion which is needed to find the cache).
“And soon, three pale green dollops hung from the carved-out leaves, each studded with four gold beads--so gold they looked to be mineral--not animal--a miracle that kept us amazed as the walls grew clear and the transformed things broke through, pumped fluid in their wings, dried off--and flew.”
The Butterfly Pavilion and Insect Zoo are live exhibitions that help make science interactive and fun. The Butterfly Pavilion features over 300 live tropical butterflies from around the world demonstrating co-evolution with plants. The Insect Zoo offers a showcase of arthropods with tarantula feeding demonstrations and an opportunity to touch and hold live arthropods.
by Joan Murray
In addition to the arthropod biology exhibited in the Insect Zoo and Butterflies + Plants: Partners in Evolution, a tremendous amount of entomological research goes on behind-the-scenes. The Department of Entomology at Smithsonian houses a collection of 35 million insect specimens, including about 3 million Lepidoptera (butterflies and moths). These collections are used both for basic research on evolutionary relationships and ecology and for applied research critical to agriculture, including pollination and biological control. A major current focus is documenting the Lepidoptera of South America, the richest and mostly poorly known fauna in the world.
Information to find the cache
To obtain the latitudinal coordinates for the cache you will have to visit the Insect Zoo and Butterflies + Plants: Partners in Evolution exhibitions at in the Smithsonian Institution’s National Museum of Natural History. You will then proceed to a series of waypoints in the outdoor Butterfly Garden to obtain the longitudinal coordinates to the final. The Insect Zoo and Butterflies + Plants: Partners in Evolution exhibitions are on the second floor of the Museum.
In the exhibit area, outlined in red, you will collect the information to complete the latitude for the final cache.

NMNH GEOTOUR GEOCOIN.
Critical requirements and rules for the award of the geocoin are here.
1) The Original 9 caches of the NMNH GeoTour must be completed.
2) Two (2) photographs are required. Posted with your found log. (This is not an ALR as you may log a find on these two caches without posting a picture. It is a requirement to be awarded a geocoin. In other words – no photos no coin but your found log will stand).
a. Photo of an adult at GC3RRWA "CINMAR" with the log book clearly next to the face. Do not expose the code word in the photo.
b. Photo of an adult at GC3T24J “Leave it to Beaver” with the log book clearly next to the face. Do not expose the code word in the photo.
3) A completed Passport with the required code words sent to the address listed on the Passport.
4) One (1) coin per household or mailing address. If there are multiple geocachers in a household who have completed the tour, only one (1) coin will be awarded to that address.
5) The passports that have been received prior to January 1, 2016 will be awarded one coin without having to meet item 1 above, and these rules were not in effect for the NMNH GeoTour at that time.
6) January 1 will be the date of publication of these requirements to earn the geocoin.
