Imitating Terrestrial Insects - Ants,
Hoppers and Other Terrestrials:
Recommended Prerequisites: Getting Started, Knots and Rigging
Technique, The Perfect Cast, Perfect Presentation & the Understanding
Trout series.
Terrestrial insects are non-aquatic insects that developed
from eggs laid on dry land that usually only get into the
water accidentally while they are in the adult stage of life.
Grasshoppers:
Family: Acrididae (Common Grasshopper,
Short-Horned Grasshopper)    
Some streams have such concentrations of
grasshoppers that trout hold near the banks in
anticipation of one getting blown into the
water. These streams are usually surrounded
by a lot of weeks or grass. Streams located in
grasslands, sage fields and meadows are idea
for summer and fall hopper activity. The more
grass and shrubs there are along the shoreline,
the better the hopper fishing is. This simply
means more hoppers are going to make the
mistake of getting in the water.
Grasshoppers vary greatly in size not only by specie,
but also depending on how old they are. Hatching
from eggs, they begin life as a nymph, emerge and
then continue to grow to their full adult size. They
usually emerge in the late spring or early summer and
stay around available as trout food until the fall. This
of course, depends greatly on the location of the
stream or lake. Northern locations have a much
shorter season than the southern streams and lakes.
They can usually stay around long enough to survive at
least the first frost of fall.  
and I would be sure to leave
the terrestrials in this alone.

Most grasshoppers seem to rely on their strong legs
to fly just about as much as they do their wings. They
are not very good fliers. They seem to jump and then
fly as best they can to land wherever they may
happen to land. Most of them stay airborne for only
a short time.
Crickets:
Family: Gryllidae
Specie: Gryllus (common field cricket)
Crickets may not be real important, in terms
of quantities consumed by trout, but trout
take them readily at times when they are
available. In some places, they are more
numerous than grasshoppers. Crickets
occasionally fall into the water and
sometimes get washed into the water by
heavy rains. They are good jumper but can’t
fly as such. They can and often do, just
jump into the water.
Forested areas, more so than grasslands,
usually have cricket populations although
they can be found just about anywhere.  
They are great searching patterns when
nothing else is hatching. The unmistakable
chirp that crickets make will tell you when
they are present.
Crickets are usually black or brown but
some are a green color. They vary in size
from one-quarter of an inch up to an inch
long. Crickets lay eggs that hatch into
nymphs that develop into adults in late
summer and fall. They live less than one year.

Ants:
Family: Formicidae
Genus: Camponotus   
Specie: Pennsylvanicus (North American
Black Carpenter Ant)
Ferrugineus (Red Carpenter Ant)
Nearcticus (Smaller Carpenter Ant)
Each season colonies of wingless ants begin a
migration or movement in a pattern that may end at
the edge of the water.  These wingless ants tend to
fall off vegetation overhanging the water. Places
where slow to moderate current runs against banks
with lots of vegetation such as shrubs, weeds and
grass are ideal locations for ants to get into the
water.
Wingless ants float and consequently, they can
sometimes be spotted on the surface of the water.
Anywhere there is adequate depth for trout, and
that isn’t as deep as many anglers think, especially
where undercut banks are in close proximity to
overhanging vegetation, there are most likely going
to be ants in the water at one time or another
during the season.
Cicadas:
Family: Cicadidae
Genus: Homoptera
Over a thousand species.
Usually green with red and black markings.
An inch long. Size 6. This is a large tree
hooper terrestrial insect that trout love. They
fall into the water from trees overhanging the
banks as well as other streamside vegetation.
Leafhoppers:
Family: Cicadellidae (Leafhopper)     

Leafhoppers also called treehoppers, plant hoppers, jassids and other common names. They are
green, yellow, and some are brown. The jassids or euryemla supp are black with white, with red and
creamy yellow markings. When disturbed they either fly or hop away. Nymphs …Size 16-20
Common on the grassy banks of slow moving limestone streams.
Budworms:
Choristoneura occidentalis (western spruce  budworm)
Spruce budworms moths are found under spruce trees. They are terrestrial but do get into the water
very often. Moths are a dull gray with brown spots that are usually a size 10 or 12.. The wings are gray
and sometimes charcoal colored.  
The larvae have black heads and green or brown bodies. In late Spring, the larvae emerge and the
adults or moths emerge in the summer months.
Beetles:
Bees, Wasp, Spiders, and More:

James fishing a hopper at the Gallatin
River, Montana
No, I would not try to
fish live bait in this case.
Yes, both green and brown grass
hoppers can exist on trout
streams at the same time.
Angie asking if she has on the    
right color of hopper. Good           
question!
A Beautiful Green Grass Hopper
Inchworms. Loopers and Spanworms:
Family: Geometridae
Inchworms are the common name for the larvae of moths. They are also called loopers, spanworms,  
measuring worms and other names. Inchworms can be green, gray, brown or black. At times the worm
like larvae will suspend several inches from limbs on a silk thread. This activity occurs when they are
ready to pupate. During this time is common for them to fall into the water.
An excellent time to try an inchworm fly, would be when you spot a few of them hanging from tree
limbs. If you have not seen any of them on the banks, it very unlikely there is any in the water and you
would most likely be wasting time fishing imitations of them. Notice we said “most likely”. Yes, that is
to cover the exceptions that always seem to occur when someone makes an outright statement about
fishing. If you had never seen an inchworm in your entire life, it would be certain one of our viewers
would catch the larger brown trout in North America just to prove us wrong.   
This fly fishing video teaches you how to fish imitations of terrestrial insects that trout feed on. It is
the most complete fly fishing dvd ever done on this subject.
