Hello All, this is probably a very silly question but does anyone know whether any butterflies are known to scent mark their territories?
And also, do any butterflies have scent sensors ( chemical sensors I suppose they'd be called ) on their feet?
Thanks in advance

Re: Scent Marking By Butterflies
Hoggers,
I'm sure I've read that female butterflies test foodplant suitability with their feet. I assume this is scent rather than touch.

Re: Scent Marking By Butterflies
Aren't the 'brush footed' butterflies front legs modified for exactly this reason, to 'taste' the foodplant before they lay?

No such thing on this forum, unlike some others I could mention, but let's not go thereHoggers wrote:Hello All, this is probably a very silly question

Not that I'm aware of; it would seem a dreadful waste of limited resources if they then had to move on, since (I think) the emission of pheromones (chemical signals) requires some physical change in the androconial (scent) scales. But I must admit that I've not looked into this in any detail, and am willing to be corrected by someone in the knowHoggers wrote:... but does anyone know whether any butterflies are known to scent mark their territories?

I think most of them do. Again, I'm here to learn tooHoggers wrote:And also, do any butterflies have scent sensors ( chemical sensors I suppose they'd be called ) on their feet?

Re: Scent Marking By Butterflies
From what I've read, female butterflies in particular have the sensory capacity to detect 'smells' via their feet.
Re: Scent Marking By Butterflies
Thank you to all who took the time to help me with my questions.
Some will have guessed that my interest in this matter comes from watching male Small Coppers - as part of their daily routine they will fly from plant to plant within their territories walking down the stems or across the leaves whilst quickly tapping their feet and I've been wondering why they do this.
Perhaps tapping disturbs residual chemical deposits on the plant surfaces which can then be detected by "scent" receptors on the feet?
It's purposeful behaviour, apparently "hard wired" into the Small Copper"s daily routine. They certainly seem to be investigating something. And as I've seen only males do it I wonder if it's sexual behaviour, ie, (just a guess ) "scenting" the presence of females that may have been in the area?
I'm not a scientist and haven't a clue about such things - I'm just trying to understand something I've seen Small Coppers do

Re: Scent Marking By Butterflies
Perhaps it's some way of attracting females? The coppers version of a display flight? Since butterflies see more colours than we do perhaps the angle of the wings makes them stick out in some way? Or alternatively a way of telling rival males that this territory is occupied....or both maybe? Just thinking out loud ![Confused :?](./images/smilies/icon_confused.gif)

All ideas gratefully received, Buggy!
I did wonder if he might be scent marking his territory to keep other males out and attract females. Last Sunday I watched one male oust another from a patch of brambles. Once the original tenant had gone the victor made a few reccy flights around the patch and obviously did not encounter the first male ( he'd gone ). Once he knew the patch was now his the victor did a stem dance,tap dancing over random leafs on the bramble patch. And I wondered : was he marking it as his own?
