Living Laboratory

• Phacelia flowers
• Praying mantis
• Mealyworms
• Slugs
• Worms
• Wee beasties (Paramecium)

3

• Phacelia flowers grow in the spring in the
  classroom and plant out in summer.
• Purpose provides pollen and nectar for
  beneficial insects which
• prey on insect pests and for honey bees and
  bumble bees.
• Investigate
• insect visitors.
• compare pests in areas
• with/without phacelia.

Beetles Phasmida, Stick-Insects Dictyoptera,
Cockroaches and Praying Mantids Hymenoptera,
Wasps, Ants and Bees Lepidoptera, Butterflies
and Moths

Praying mantis egg case

• Picture shows 11 eggs intact.
• 5-6 months in egg case (ootheca) until hatching
  in spring.
• Case taken from warm north facing garage wall.

7

• Food supply
• Nymphs fruit flies (Drosophila spp.)
• Adults flies, wasps, bees, grasshoppers
• Rear adults singly in ventilated container with
  water source and string across container for skin
  shedding / hanging by instars
• Investigations
• Temperature for development
• Orientation of ootheca on development

8

• Mealyworms (Darkling beetles)
• Class Insecta
• Order Coleoptera
• Family Tenebrionidae
• Genus and species Tenebrio molitor

Purchase from Pet store and
bait shop (Animates)Feed with bran, oatmeal,
fresh oats, wheat bran. Sliced potato, carrot,
apple (water source)Uses Food source for
reptiles, fish, wild birds, fishing baitRequire
Ventilation and dark preference

• Orientation experiments
• Ranging no knowledge about where to find
  resources
• Local searching more restricted search

11

• Ranging and Local Searching
• Place a bug in the centre of a piece of filter
  paper and moisten paper at radius of 10cms (leave
  dry gaps around radius)
• If bug goes through gap re-position in centre.
• Repeat with other bugs.
• Results Ranging occurs until moisture is
  detected and then localised searching begins.

12

• Further ranging investigation
• Place bug on wooden object and use paintbrush to
  keep it moving along.
• Note direction it turns
• at T junction. Repeat
• with same bug.
• Repeat with 4 more
• bugs.

13

• NEXT.... Use the bend right T junction
• Try the bend left and T junction.

14

• Repeat with 20 bugs for each.
• How many turn left after the right bend or right
  after the left bend?
• Investigate the same with different starting
  orientation to light source.
• Repeat with 4 more bugs.

15

Investigate the same with different starting
orientaion to light source. Repeat with 4 more
bugs.

about 15 species Life History Favours damp, dark
habitat, wingless, not a household pest

• TIP -Put into deep freeze to slow them down to
  transfer to other containers.
• Investigations
• Leg movement in which order?
• Life cycle and egg laying studies.
• Dissection of gut

Slugs

Slug eggs Keep moist under soil and small
rocks Investigations Temperature for hatching

Protists and wee pond beasties. Use dropper to
take liquid from leaf bases of bromeliads (from
hot house Botanical Gardens) Transfer to
container and add straw. (Protists feed on the
bacteria that rot the straw) Make sure the
contents does not dry out.
