Australian cricketers Almost all of the names given to Australian crickets have been assigned by overseas entomologists. One of the reasons for this book is to attempt to stimulate interest on

the part of local students and professionals in this important group of insects. There are

wonderful opportunities for not only taxonomic study, but also for ecological,

behavioural and acoustic studies. Some of the most important describers of Australian genera and species are presented below.

Conservation

No single cricket species is of conservation concern even though many species are

known from very restricted areas.Probably themost important consideration should be made is conservation of habitats. This is important in coastalareas,such as along the coast of Western Australia where housing development, agriculture, including wheat and grape culture is rampant. Loss of the Coastal Sand Plain flora and fauna is

By eating crickets and other insects, we will reduce our reliance on traditional large-animal farming, including factory farming. Ultimately, this will reduce water use,land use and pollution. In addition to all of the environmental benefits of entomophagy, insects are a healthy, alternative source of protein. For example,100g of cricketscontainsjust5.5g of fat and 121 kcal, with almost 13 g of protein (see Table 2). Compare this to

100 g of 80lean ground beef, which has  ̄20 g of fat and 254 kcal. While beef does have more protein than a serving ofcrickets, it also has a much higher calorie and fat

content, with higherlevels of saturated fat.

How to eat insects

Incorporating insects into one's diet is relatively easy, especially so with the rise of

many companies specialising in pre-cleaned and cooked insects and insect flours all over the world. Although crickets and other invertebrates are,for the mostpart,safe to eat when cooked, it is important to avoid catching and eating insects that are found in

one's backyard, as they might have been 60

Recent changes have resulted in the definition of the genus Mundeicus has resulted in its now being regarded as a

subgenus of Hemiphonus. The genus Tamborina has had species transferred to it from Madasumma. This can be quite confusing to the uninitiated to taxonomic practice.Refer to the species list on p.372 forcomplete listings of species. All3 of these taxa are very closely related. Madasumma

comprises rather similar-appearing crickets and it could be easily confused with the other 2. This is reflected in its taxonomic

history. Other genera are not as difficult to separate. Use the lists of characters below to

Genus Myara Otte & Alexander (Meteor Crickets)

Myara is wholly confined to the Australian continent with the distinctive species inhabiting stems and bark of trees. The group has an appropriate common name based on the behaviour of the crickets- they are very quick to escape. The genus is similar in overall appearance to Eurepa but

can be easily identified by examining the male concealed genitalia.In Myara the ectoparameres lack downwards projecting

flanges. The biology and ecology of the 2 genera are similar. The crickets inhabit

trees and live in bark crevices or under loose bark. Males are vocal and a given species may be common at a suitable

instar-the developmental stage between moults

diapause-the delay in development in response interval-the distance in time from the end of one sound unit until the beginning of the next to regular and recurring periods of adverse labial palpi - the segmented structures environmental conditions emanating from the labium; there are three dimorphism - difference in appearance of

individuals, usually referring to sex

distal- near or towards the free end of any appendage

dorsal field-upper flat horizontalsurface of tegmen

ecdysis-the process of moulting

segments

labrum-the lower lip'or flap just below the

clypeus that covers most of the mandibles and

other mouthparts

lateral lobe-the two lateral and vertical sides of

the pronotum endemic- restricted to a given geographical macropterous- with tegmina and wings fully

region

epiphallus-uppermost prominent part of male

genitalia

fastigium of vertex-the anterior part of the vertex often projecting anteriorly between the

eyes

developed, exceeding or at least reaching the end of the abdomen and overlapping dorsally

maxillary palpi-attached to the maxilla of the

mouthparts and bearing five segments as

opposed to the three-segmented labial palpi

mesopterous-semi- or half-winged, capable of flagellum- the thread-like and most elongate gliding and not usually of full light portion of the antenna mesothorax-the second thoracic segment

380

GLossARY metatarsus, pl. metatarsi-the first segment,sternite- one ventral segment usually, of the hind tarsus stridulatory pegs - the minute teeth on the metathoracic- referring to the third thoracic underside of the stridulatory vein segment stridulation-sound production produced by macropterous- with greatly reduced tegmina rubbing the tegmen against a raised vein on and wings, often widely separated

mirror-section of male tegmen(Fig.9 on p.47)

morphs-any of the genetic forms that account

for polymorphism

ocellus, pl.ocelli-three small, simple eyes: one

the opposite tegmen

stridulum-stridulatory vein on male tegmen (Fig. 9 on p.47)

subgenital plate - last ventral abdominal

segment

in the middle on the frontal ridge and the supra-anal plate- the last abdominal tergite

other two, if present, near the inner sides of

covering the anus from above

having a line of separation

populations in the same area

the compound eyes symmetrical-of similar shape or development occiput-the posterior part of the head merging on the right and left sides anteriorly with the vertex and not usually sympatric- the occurrence of two or more

pedicel- the second antennalsegment prognathous - the mouthparts projecting

forward (p.235)

pronotum (also pronotal disk)-the dorsal

horizontal of the pronotum connecting the

two lateral lobes

tarsus,pl. tarsi- the three-to five-segmented

distal part of the leg

tegmen, pl. tegmina- the first pair of wings or

the fore wings

tibia-the part of theleg between the femurand the tarsus

proximal-the part of an appendage which is tergite-a single dorsal body segment nearest to the body, as opposed to distal tribe-a subdivision of a subfamily containing pulse- refers to a group of stridulatory tooth one or more genera, the name of which ends strikes usually cause by a single closing stroke

of the tegmina

pulse rate-number of pulses per second rostrum-generally synonymous with frons but used when it projects in front of the antennal

sockets scape-the first antennal segment

sclerotised- hardened cuticle song-a group of chirps or trills that is repeated

in ini

trill- a long series of pulses

trochanter-a small segment between the coxa

and femur

univoltine-having one generation per year

ventriloquial-sound production appearing to come from elsewhere

vertex-the top of the head merging behind with

the ociput

spine - teeth, denticulations and other wings- the second pair of wings, positioned immoveable tooth-like structures under the first pair and usually fan-like with spermatophore - a membranous or sticky package of capsule containing sperm that is

transferred from male to female during copulation or courtship spurs-moveable structures with a socket;larger than spines and articulated, often curved

the tips often protruding from beneath the tegmina; in some species they are reduced or

absent

Orthopteroid food mix This formulation, or slight variations thereof, has been adopted by zoos, museums and

commercial growers for rearing a variety of insects. It is simple and provides necessary nutrients to culture orthopteroid insects. Consult Henderson et al.(2008) for the best ways

to keep captive orthopteroids. l cup natural, not toasted, muesli 4 tablespoons flake fish food

2 tablespoons birdseed mix (fine grains)

2 tablespoons bee pollen (available from health food stores) 1/2 cup Guinea-pig pellets

You can add/substitute the following: 1 tablespoon Repcal Juvenile Bearded Dragon Pellets

l tablespoon Reptile Multivitamin Powder

1 tablespoon Wombaroo Reptile Supplement 2 tablespoons Wombaroo Finch Soft Food Store in the refrigerator for freshness and to avoid mould. Cautionary note: We have detected colour change in some crickets when using the above mix. We have not done thorough tests but believe that a green dye in the flake

fish food is responsible for addinggreen to otherwise brown crickets.See Trigonidum

boundilla.
