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.

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

estimated to reach 9 billion people by 2050. To accommodate this estimated world population, current food production rates will need to double and, with land already

scarce,expanding farming acreage is hardly a viable or sustainable option. 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

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

This genus comprises 58 species distributed in Oceania and New Guinea. A single described species occurs in Australia and was originally described in Aphonoides. We

have an additional species from Iron Range, Qld. This genus differs from Aphonoides in

its slightly different habitus. Males have an elongate, slightly divided subgenital plate

and a supra-anal plate with a median projection; the epiphallus is divided and the

arms are apically divergent. The spermatophore is elongate and black as occurs in some Aphonoides species. The tip

to males lacking a stridulatory file, both sexes have the median and radius veins fused briefly in the anterior third. The male epiphallus is strongly asymmetrical

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

groups mostly based on features ofthe very

distinctive male genitalia. anterior margin of the pronotum to the tip of the abdomen in both sexes. Otte and

Alexander divided the genus into 4 species


The Wittllio Group

Epiphallus covered in thick black dorsal setae. Females wingless.


The Peekara Group

Epiphallus with thin,pale dorsal


Females wingless.

The Witilliko Group Salmanites wittlliko Otte & Alexander


The Ninblla Group

Easily recognised. This species has the

Epiphallus hairless dorsally.

Females wingless in many species but

minute tegmina in S. allaris.

The knurra Group

frons not black under the eyes (Fig.26E),

but usually with a dagger-like stripe that extends nearly to thelabrum. This can be

a rather broad blotch in some specimens

Males unknown!
