I'm glad I did! Not only did I manage to photograph a nice Green Shieldbug nymph (which I've posted on my post on Green Shielbugs (April 17th 2007)-HERE, I saw a few other little insects which I'll briefly post on here (and above).
The first of these is another species of Mirid - this one being (I think), the Lucerne Bug. Look for the very distinctive pale cuneus (V shaped), 2 dark pronotal spots (not visible here) and if you have the eyes of a hawk, very spiny tibia! It is relatively common, even in gardens, and tends to feed mainly on Lucerne (obviously) and Clover (of which the Lower Paddock has masses...).
NB. I suppose there is a possibility that this Mirid could be Calocoris roseomaculatus (no common name) which looks very similar to the Lucerne Bug, but with rosy markings on its wings. I may get corrected by a real entomology expert on this...
NB. 25/10/07 After a month or so of casual research, it turns out this could be the Tarnished Plant Bug, Hippodamia variegata. Very confusing, these Mirid Bugs!
