6 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, grasshoppersRear adults singly in ventilated container with water source and string across container for skin shedding / hanging by instarsInvestigations:Temperature for developmentOrientation of ootheca on development

10 Purchase from:. Pet store and bait shop (Animates) Feed with: 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 bait Require: Ventilation and dark preferenceOrientation experimentsRanging – no knowledge about where to find resourcesLocal 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 turnsat T junction. Repeatwith same bug.Repeat with 4 morebugs.
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.
16 Cockroaches: (cerci in both sexes) Male (with stylets) Female (without)
