There certainly has been a third brood out at Calley, and since they're still flying on Walmgate Stray I guess they might still be out at Calley. I haven't been in for a couple of weeks though.millerd wrote:Is there a third brood out now at Calley Heath do you know?
That is certainly one of our top hypotheses for the observed pattern. SImilarly, the White Campion plants tended to be taller than the surrounding sward, which may also have helped them to stand out.PhilBJohnson wrote:I thought that some of those white flowers under street lamps, that were more frequently pollinated, were more obviously seen by moths there because of white's reflective qualities. (a moonlit or mute point possibly, for the future).
We did wonder about this but it's unlikely to have had an impact in our study, because the White Campion plants were only under the street lighting treatments for four days each whilst being pollinated, but were all in the same greenhouse under the same conditions beforehand (when growing) and afterwards (when setting seed).PhilBJohnson wrote: Some plants are grown indoors (particularly in aquariums) with grow lamps (the better lights for photosynthesis).
Yes. Off the top of my head, from the most abundant families, the Erebidae are most strongly attracted to light, and prefer light right at the blue/ultraviolet end of the spectrum (i.e. LED lamps). Noctuidae are slightly less strongly attracted but also prefer blue/UV. Geometridae are less strongly attracted still, and may have more of a preference for longer blue/green wavelengths. But this has not been very solidly established yet.PhilBJohnson wrote: Are different moth species attracted more to different lamp types than others?
I've had the same thought in parts of the Yorkshire Wolds (which are also chalk!). We still have Marbled White in quite a few places, and Brown Argus breeding on Rock-rose. I can certainly picture those Blues present, especially under future climate change, though they wouldn't get there without assistance, I suspect.PhilBJohnson wrote: Just south of you in Yorkshire are the Lincolnshire Wolds (LW),(which are chalk, so possibly much different from the Yorkshire Wolds). I once lived much closer to the north and South Chalk downs, where chalk grassland species such as Marbled White, Chalkhill Blue and Adonis Blue were locally numerous.
In Lincolnshire, I thought that there was an opportunity for Chalk Grassland Habitat Restoration on the LW. I thought that some Blue species, also depended on species of ant as well as larval food plant.

Nor have I! I suspect that foraging on the ground is quite normal behaviour for this species when it is windy (which it was, last Sunday - extremely!). But we just don't see it because usually it happens somewhere in the middle of the reedbed, rather than right beside a busy footpath!David M wrote:I've never seen one display itself so openly.
