• This sequence of photographs shows a female Hazel Leaf-roller Weevil receiving the attention of two males. Both are presumably intent on mating with her (although neither is actually doing so) and there is quite a lot of posturing going on between the rivals involving much touching of antennae and deliberate articulation (?clicking) of neck joints. It was not evident from watching this behaviour whether this movement produces any actual sound but the beetles certainly appeared to be signalling to one another. It is speculated that the extended length of the head of this insect may be associated with this activity. The female seems to be completely unconcerned as she is merely continuing her leaf-rolling activities.

• The BBC 'Home Planet' programme has recently linked into this page following a discussion about the Hazel Nut Weevil Curculio nucum. This is actually an entirely different species and information about this beetle may be obtained on: http://www.inra.fr/Internet/Produits/HYPPZ/RAVAGEUR/6curnuc.htm. 'Home Planet' visitors to this page are, of course, very welcome to take a look around this site before following the link!
