Adopted on April 14, 1939, the Blue Hen chicken had long been used as a motif in numerous political campaigns and in many publications. During the Revolutionary War, the men of Captain Jonathan Caldwell's company, recruited in Kent County, took with them game chickens that were said to be of the brood of a famous Blue Hen and were noted for their fighting ability. When not fighting the enemy, the officers and men amused themselves by pitting their Blue Hen chickens in cockfights. The fame of these cockfights spread throughout the army and when in battle, the Delaware men fought so valiantly that they were compared to these fighting cocks.

State Marine Animal:
Recognizing its great importance and value, the horseshoe crab was designated as Delaware’s official marine animal on June 25, 2002. These invertebrates contain a compound, limulus amebocyte lysate (LAL), that is used to detect bacterial poisons in certain medications, vaccines and medical devices. Chitin, a natural polymer found in the horseshoe crab’s shell, is used to make bandages. The horseshoe crab is used in vision studies, because their complex eye structure is similar to the human eye. It is the principal food source for over a million shore birds. Delaware Bay is the home to more horseshoe crabs than any other place in the world.

State Wildlife Animal:
Adopted June 10, 2010, the grey fox is a unique and primitive species, believed to be between 7 and 10 million years old, which is indigenous to Delaware. It is a swift and powerful animal capable of running up to 28 miles per hours and the only member of the canid family which is able to climb trees. The fourth grade students at Joseph M. McVey Elementary School, as part of teacher Paul Sedacca's lessons on persuasive writing, suggested that the grey fox be designated as Delaware's official state wildlife animal. Since it does not hibernate, the students said that it is "always ready like our soldiers at Dover Air Force Base".

December 7, 1787
"Liberty and Independence"
"The First State"
Delaware is known by this nickname due to the fact that on December 7, 1787, it became the first of the 13 original states to ratify the U.S. Constitution. “The First State” became the official State nickname on May 23, 2002 following a request by Mrs. Anabelle O'Malley's First Grade Class at Mt. Pleasant Elementary School.
Delaware Code Title 29 § 318
"The Diamond State"
Thomas Jefferson gave this nickname to Delaware, according to legend, because he described Delaware as a "jewel" among states due to its strategic location on the Eastern Seaboard.
"Blue Hen State"
This nickname was given to Delaware after the fighting Blue Hen Cocks that were carried with the Delaware Revolutionary War Soldiers for entertainment during Cockfights.
This nickname was given to Delaware due to its size and the contributions it has made to our country as a whole and the beauty of Delaware.
The town of New Castle, a port on the Delaware River, became the colonial capital of the "Three Lower Counties" (Delaware) in 1704. Under Pennsylvania's Deputy Governor John Evans, the assemblies of the colonies of Pennsylvania and Delaware separated though legislation enacted in both assemblies still required the Pennsylvania governor's signature. In November of 1704, four representatives from each county - New Castle, Kent, and Sussex met in the town and passed the colony's first two laws. One confirmed all laws previously enacted by the joint assembly of the colonies of Pennsylvania and Delaware. The second law changed the number of representatives from each county from four to six.
William Rodeney (as he spelled his name) of Kent County, grandfather of Caesar Rodney, served as the first-known speaker of the assembly. His grandson, Caesar, presided over the last colonial assembly in Delaware. The "Three Lower Counties" remained a part of Pennsylvania until 1776 when economic, cultural, and political differences fostered a permanent separation. The capital was moved from New Castle to Dover in 1777.
"Delaware became a state on June 15, 1776,..." on September 11, 1776, at a special constitutional convention,... Delaware enacted the Delaware Declaration of Rights...
Delaware became a state on June 15, 1776, when the Delaware Assembly formally adopted a resolution declaring an end to Delaware’s status as a colony of Great Britain and establishing the three counties as an independent state under the authority of “the Government of the Counties of New Castle, Kent and Sussex Upon Delaware.” After the signing of the Declaration of Independence on July 4, 1776, the Delaware Assembly called a special constitutional convention, which assembled at New Castle on August 27, 1776. On September 11, 1776, the convention enacted the Delaware Declaration of Rights, similar in style to the later U.S. Bill of Rights. On September 21, 1776, the convention enacted the first Delaware Constitution. That first constitution served the state for a period of some 16 years until Delaware’s second state constitution was enacted by another constitutional convention in 1792. Our third state constitution was enacted in 1831 and our fourth, and current, constitution was enacted in 1897. Today, Delaware has a cabinet form of government.
The General Assembly, Delaware's lawmaking body, is comprised of a State House of Representatives, whose 41 members are elected for two-year terms, and a State Senate, whose 21 members are elected for four-year terms. Half of the Senate seats are contested in each general election.
The State Supreme Court consists of a chief justice and four associate justices. All members are appointed by the governor, with confirmation by the Senate, for a term of 12 years.
"Colonial Blue" & "Buff"
Adopted on July 24, 1913, the state flag has a background of colonial blue surrounding a diamond of buff color in which the coat of arms of the state of Delaware is placed.
Below the diamond are the words "December 7, 1787," indicating the day on which Delaware was the first state to ratify the federal Constitution. Because of this action, Delaware became the first state in the Union, and is, therefore, accorded the first position in such national events as presidential inaugurations. According to members of the original commission established to design the flag, the shades of buff and colonial blue represent those of the uniform of General George Washington as shown on a specific plate from an official U.S. Army publication.

Oh the hills of dear New Castle,
and the smiling vales between,
When the corn is all in tassel,
And the meadowlands are green;
Where the cattle crop the clover,
And its breath is in the air,
While the sun is shining over
Our beloved Delaware.
Oh our Delaware!
Our beloved Delaware!
For the sun is shining over
our beloved Delaware,
Oh our Delaware
Our beloved Delaware!
Heres the loyal son that pledges,
Faith to good old Delaware.
Where the wheat fields break and billow,
In the peaceful land of Kent,
Where the toiler seeks his pillow,
With the blessings of content;
Where the bloom that tints the peaches,
Cheeks of merry maidens share,
And the woodland chorus preaches
A rejoiceing Delaware.
Dear old Sussex visions linger,
Of the holly and the pine,
Of Henlopens Jeweled finger,
Flashing out across the brine;
Of the gardens and the hedges,
And the welcome waiting there,
For the loyal son that pledges
Faith to good old Delaware.
From New Castle's rolling meadows,
Through the fair rich fields of Kent,
To the Sussex shores hear echoes,
Of the pledge we now present;
Liberty and Independence,
We will guard with loyal care,
And hold fast to freedom's presence,
In our home state Delaware

On July 2, 1996, belemnite was named as the official fossil of Delaware. The Martin Luther King, Jr. Elementary School (Wilmington) third grade Quest students of Kathy Tidball suggested honoring the ancient and noble belemnite as our State fossil.
The belemnite was, in essence, a squid with a conical shell. It is an extinct member of the phylum Mollusca, which includes clams, snails, squids and octopuses. Belemnite fossils can be easily found along the Chesapeake and Delaware Canal, which is where the Quest Students collected specimens during a field trip.

The channeled whelk is a very large predatory sea snail belonging to the family Buccinidae. Shells of the channeled whelk typically reach 5 to 8 inches in length. The shell is smooth and subpyriform (generally pear-shaped), with a large body whorl and a straight siphonal canal. Between the whorls there is a wide, deep channel at the suture, and there are often weak knobs at the shoulders of the whorls. Finely sculpted lines begin at the siphonal canal and revolve around the shell surface.

Adopted on June 10, 1999, the Tiger Swallowtail ( Pterourus glaucus ) was declared the State’s official butterfly. The tiger swallowtail, a large, yellow, black-striped butterfly, is indigenous to Delaware and can be seen in deciduous woods, along streams, rivers, and wooded swamps, and in towns and cities throughout Delaware. Three butterflies were chosen by students of the Richardson Park Learning Center as possible State butterflies; then 1,611 out of 3,175 public and parochial students all over the State voted to suggest to the Legislature that the tiger swallowtail be named the State’s butterfly.
Delaware Code Title 29 § 315
On May 4, 2005, the Stonefly, (Order Plecoptera ), was designated as Delaware's State macroinvertebrate, because it is an indicator of the excellent water quality in the State. The designation of the stonefly was a means whereby Delaware State government could recognize the importance of excellent water quality and the vital role played by healthy aquatic ecosystems in Delaware.
Designating a State macroinvertebrate is a highly appropriate means to raise public awareness of water quality issues, and complement citizen action programs like Delaware Stream Watch. Through their participation in the Delaware Stream Watch Program, the designation of the stonefly as the official State macroinvertebrate was supported by the following schools:
Gunning-Bedford Middle School, Salesianum High School, Delcastle Technical High School, Dickinson High School Environmental Club, The Independence School, Springer Middle School, St. Andrews School, and The Charter School of Wilmington.
By designating the stonefly as its State macroinvertebrate, Delaware once again demonstrated its leadership as the First State, because currently, no other state in the United States has designated an official State macroinvertebrate to accompany their State symbols, such as their State flag, State flower, State bird, State bug, State butterfly and State marine animal.
Delaware Code Title 29 § 320
Passage of the act to adopt the Peach Blossom on May 9, 1895, was prompted by Delaware's reputation as the "Peach State," since her orchards contained more than 800,000 peach trees yielding a crop worth thousands of dollars at that time.
Delaware Code Title 29 § 308
Sweet Golden Rod
Adopted June 24, 1996, Sweet Golden Rod ( Solidago odora ) was named Delaware's State herb. Members of the International Herb Growers and Marketers Association of Delaware suggested that the herb "Solidago Odora", commonly known as "Sweet Golden Rod," because of its beautiful golden blossoms, would be especially appropriate as the designated herb.
Sweet Golden Rod is both indigenous to Delaware and widespread throughout the State where it is commonly found in our coastal areas and along the edges of marshes and thickets.
Delaware Code Title 29 § 313
Adopted May 1, 1939, the American Holly ( Ilex opaca Aiton ) is regarded as one of Delaware's most important forest trees.

On July 30, 2009, peach pie was designated as Delaware's official State dessert. Peach farming is an important part of Delaware's agricultural heritage, as the peach was introduced to Delaware in Colonial times and expanded as an industry in the nineteenth century. Delaware was the country's leading producer of peaches for part of the nineteenth century, at its peak, shipping 6 million baskets to market in 1875. The fifth and sixth grade students of St. John's Lutheran School in Dover, with the support of the entire student body, suggested that peach pie be adopted as this State's official dessert because of the historical and agricultural significance of Delaware's peach farming industry.
