Male: Lower Eyes
|Class:||Animals (Animalia) - Jointed Legs (Arthropoda) - Insects (Insecta)|
|Species:||Mayfly (Centroptilum cf elongatum)|
|This Photo:||Male: Oscelli|
General Species Information:
Found in the Adelaide Hills, and elsewhere
This male was about 5mm long (head & body). The tail cerci are just under 9mm. The specimen we found keyed out to Centroptilum, and C. elongatum is the only one in this genus found in SA. It could of course be an undescribed species.
Notice the weird overhead eyes of the male; used for searching for a female (thank you to Ian Gibbins for confirming this assumption When we mentioned we couldn't think of another invert' with a 2nd pair of compound eyes, Ian also told us that they are not strictly a 2nd pair of eyes; but a genetic situation where the normal eyes split during development. This is a similar trick to the way mantids, eg, have striped eyes; and other insects have different zones in their eyes for varying purposes. Pretty fascinating stuff
