Where

 do

 you

 look

 for

 li.er?

Li#er

 is

 everywhere,

 even

 on

 this

 rela2vely

 manicured

  campus.

 When

 you

 study

 the

 brown

 food

 web,

 you

 see

  habitats

 everywhere

  For

 example

 some

 of

 the

 finest

 li#er

 is

 o?en

  embedded

 in

 a

 smooth

 lawn.

 To

 gather

 it,

 make

 your

  hand

 look

 like

 a

 li#le

 rake,

 and

 run

 it

 through

 the

 lawn.

  Again,

 grass

 li#er

 may

 yield

 different

 species

 in

  different

 numbers.

ECOLOGY

is

 slightly

 wet).

 your

 berlese

 funnel.

 

 Good

 li#er

  around

 a

 while,

 and

 has

 a

 nice

 earthy

 smell.

 The

 best

  2mes

 to

 look

 for

 li#er

 cri#ers

 is

 in

 late

 spring

 and

 early

  fall,

 when

 the

 weather

 is

 s2ll

 warm.

 Defros2ng

 li#er

  that

 has

 been

 siIng

 underneath

 snow

 may

 get

 you

  some

 invertebrates,

 but

 not

 as

 many

 as

 you

 would

 find

  when

 its

 warm

 outside.

 This

 has

 been

 provided

 for

 you

  in

 your

 field

 kit.

  Where
