HOUSE

JOINT

RESOLUTION

A

Joint

Resolution

designating

the

regal

fritillary

as

the

1

official

state

butterfly

of

the

state

of

Iowa.

2

WHEREAS,

the

regal

fritillary

(speyeria

idalia)

is

one

of

3

Iowa’s

largest

native

butterflies

with

a

wingspan

that

can

4

exceed

four

inches;

and

5

WHEREAS,

the

regal

fritillary

is

one

of

temperate

North

America’s

most

striking

butterflies

with

forewings

that

are

a

7

rich

reddish

orange

with

a

number

of

irregularly

shaped

black

8

spots

and

a

deep

orange-brown

border,

and

hind

wings

that

are

9

a

unique

velvety,

iridescent

blue-black

with

cream

and

orange

10

spots;

and

11

WHEREAS,

the

regal

fritillary

has

statewide

distribution,

12

making

it

possible

for

Iowans

to

see

adults

flying

in

summer

13

and

early

fall

in

association

with

native

prairie

habitats

14

including

upland

and

wet

prairies;

and

15

WHEREAS,

the

regal

fritillary

is

a

univoltine

species,

16

meaning

it

takes

one

year

for

a

single

brood

to

complete

the

17

four

stages

of

its

life

cycle;

and

18

WHEREAS,

in

the

fall,

the

female

regal

fritillary

may

lay

up

19

to

two

thousand

eggs

on

the

ground

near

the

growing

point

of

20

their

host

plant;

and

21

WHEREAS,

soon

after

being

laid,

the

eggs

hatch

and

the

first

22

instar

larvae

eat

only

their

eggshells

before

hibernating

and

23

surviving

the

winter

in

their

smallest

form;

and

24

WHEREAS,

in

spring

when

the

prairie

violets,

bird’s-foot

25

violets,

and

other

native

violets

begin

to

grow,

the

larvae

26

come

out

of

winter

diapause

or

dormancy

to

have

their

first

27

host

plant

meal;

and

28

WHEREAS,

while

most

butterfly

larvae

have

five

larval

29

instars,

or

growth

stages,

the

regal

fritillary

is

unique

in

30

that

it

completes

six

instars

before

it

makes

a

chrysalis;

WHEREAS,

mostly

from

habitat

losses

east

have

37

shifted

its

placing

Iowa

in

the

core

of

its

current

range;

and

39

WHEREAS,

as

efforts

are

being

made

in

the

state

to

preserve

40

prairies

and

reestablish

grassland

habitats,

the

regal

41

fritillary

is

the

perfect

symbol

to

represent

the

prairie

42

heritage

of

Iowa,

and

the

disappearance

of

this

butterfly

from

43

the

state

would

be

a

tremendous

loss;

and

44

WHEREAS,

the

general

assembly

supports

efforts

to

designate

the

regal

fritillary

as

the
