To follow Matthew's observations on colouring up, I can report that the larvae I am following here in Switzerland are a little ahead. Of nine iris cats on my daily dog-walk, 8 are coloured up and just one still green. Here are three in winter livery and the remaining summer cat, all photographed today:
Larvae are just beginning to colour up in the wild - one out of 8 seen today had started to change colour, the others were still in Lincoln green. This is slightly behind the norm, but the weather has been mild.
There's a lot of rust, mildew, spots and assorted poxes on tree leaves this autumn, presumably because of the warm, moist summer. On sallows, there's a lot of blackening on leaf tips and edges, which is displacing larvae off their favoured tips.
Here's one of today's larvae -
Seemingly, throughout the Empire many sallows have blackened off badly, shedding leaves prematurely.
A question ;
Why are some larvae now feeding voraciously while others are already immobile, dark in colour & located in odd places such as leaf - veins near the leaf base ?
Are the non - feeders doomed or are they going into hibernation at a sensibly early date ?
Puzzled of Dorset.
Here in Switzerland autumn is falling early and some of my iris cats are beginning to turn too. I'm still seeing the same 9 on my daily dog-walk - here are four of them, in different shades of green, today:
The tally for my annual standardised count of iris larvae in / around Savernake Forest is a measly 20, the lowest total in six years of diligent recording. Last year it was over 200!
Worryingly, I've found a lot of failed breeding sites, where 1st or 2nd instar larvae had been feeding. Most of these have been checked twice, just in case of oversight. It looks as though the incidence of 1st and / or 2nd instar fatality has been unusually high this year. This may be because of the cold, wet August, though I suspect it may be due to the leaves being too thick and coarse following an early and rapid spring.
Here's a trio of leaves bearing seat pads and feeding marks of lost young larvae (+ egg case bases) -
Note the leaf tip damage.
I rarely find any on narrow-leaved sallows in / around Savernake. Here's an exception - and a rare example of a larva not on a leaf tip -
