Odonata (dragonflies, mayflies)


[large rounded heads, elongated abdomens, two pairs of horizontal wings that move independently; larvae are aquatic so adults tend to be near water]
Odonata (dragon- and damselflies) vs. Neuroptera, Myrmeleontidae (antlions): adult Odonata are generally diurnal, have no easily visible antennae, have two roughly parallel sets of wings, and hold the wings away from the body at rest; adult antlions are mainly crepuscular or nocturnal, have prominent antennae, have the attachment points of the two sets of wings rather close with the rear wings angled sharply backwards, and hold the wings folded flat over the abdomen or held tentlike over the body
comment (JH): montane Songhay and northern Dogon do not usually have terms for Odonata (even as a class); by contrast, they do recognize adult antlions

suborder Anisoptera (or Epiprocta) (dragonflies)


[robust body, strong fliers; back wing broadens near the base unlike front wing; eyes usually touch; at rest, wings held horizontally or somewhat downward or forward]
dragonfly 60258

adults not usually distinguished by Dogon from adult ant-lions


suborder Zygoptera (damselflies)


[less robust, weak fliers; back wing has same shape as front wing; eyes are usually separated; at rest, wings usually held folded together above abdomen]

Orthoptera (grassnhoppers, katydids, crickets)

subordeers:

Ensifera (antennae at least as long as body, except mole crickets)

Caelifera (grasshoppers) (antennae shorter than body)



suborder Ensifera (crickets, katydids)



comments (JH): Northern Dogon languages each have a general word for ‘house cricket’. This term may also include some small local spp. of house cockroaches (not the same as the large American and European cockroaches now found in enclosed toilets in the towns. Color adjectives are used to distinguish species.

Nanga speakers know two tettigoniids: a) a very broad-winged katydid, and b) Conocephalus.

suborder Caelifera (grasshoppers)



comments (JH): Individual northern Dogon persons can often distinguish by name 12-15 species (some terms cover two or more similar spp.). Certain species are eaten by children after roasting. Each grasshopper has its own pattern of hopping, springing, or flying, and they behave differently when caught and held in the hand. Certain species are crop pests (especially millet). The species most widely known and named among northern Dogon and montane Songhay are: Chrotogonus senegalensis, Acrida group bicolor, Sherifuria haningtoni, Acorypha glaucopsis, Diabolocatantops axillaris, Anacridium melanorhodon melanorhodon, Kraussaria angulifera, Cataloipus cymbiferus, Kraussella amabile, Hieroglyphus daganensis, Oedaleus senegalensis, and Scintharista notabilis.

Saharan: grasshoppers: none; mantises: Eremiaphila monodi

Sahelian: grasshoppers: Truxalis, Ochrilidiea, Acrotylus, Oedaleus, Thisoicetrus, Acorypha, Caloptenopsis; mantises: Sphodroromantis viridis, Blepharopsis mendica; cockroaches: Acheta chudeaui

Soudanian: grasshoppers: Acrida, Catantops, Ornithacris, Acanthacris, etc.; Tettigonidae: Conocephalus maculatus, Homorocoryphus fuscopunctatus, Phaneroptera nana; cockroaches: Acheta, Brachytrypes, Pteronemobius, Trigonidium, Euscyrtus, Oecanthus, etc.

Identification: can be made using Mestre, Les acridiens... on the basis of photographs showing both outside and inside of hind leg (femur and tibia), and showing inner and outer wings. A dead specimen may be dismembered for photographic purposes. I have had best results photographing against a uniform green background. Many specimens turn out to be immature (larvae), but they usually have enough in common with mature adults (imagos) to be identifiable.

Females are usually larger and longer than males. Side photographs of males should show genitalia, which is occasionally useful in identification.

Many grasshoppers are seasonal, becoming dormant during the latter part of the dry season (e.g. January to May) and then reviving with the rains. Those that are active year-round are so indicated below. The best time to collect mature adult specimens depends on the species, generally either the latter part of the rainy season (September) or in the first months of the dry season (October-December).
