I reckon you're onto something there Trevor, I can't imagine the Waitrose faithful assaulting their noses with the smell of Tuna fish

22 Small Pearl-bordered Fritillary, 30-05-2016 Bentley Wood
Another coincidence with a very high probability – my first SPBF of 2016 came on the same date as in 2015. Locally this was the species which had the worst year. I saw a single Small Pearl all year! To slightly mitigate this doom and gloom it should be noted that I did visit as they were first appearing and I didn’t venture farther than the Eastern Clearing, plus the weather was less than adequate but a singleton? Very poor and very worrying as for a while now the population at Bentley seems to have been thinning. Usually the Pearl gets all the attention so perhaps it’s time the local branch turned the spotlight on this species? It wasn’t just me, others too found the going hard for this species at Bentley, in some cases there were even fights breaking out as people strove to get a shot.
Hopefully the few that were encountered were particularly fecund and we might see a turn around this year.

Unlike their smaller cousins the PBF seemed to be doing okay in 2016. Again I kept to the Eastern Clearing but I saw slightly more here this year and after a later start they held up well so I was able to encounter them over three visits. The first was when they’d just emerged, then there was the furore over the aberrant and the final visit was when the Small Pearls were on the wing, though by then the Pearls were looking a shadow of their former selves.
The aberrant was the obvious highlight of the year for this species and as some have suggested the melanism has a genetic basis I’ll be looking out for other melanics this year, fingers crossed!
24 Dark Green Fritillary, 26-06-2016 Duke Site
If the plight of the SPBF was a depressing start to the Frits tally then the PBF was a welcome upturn and things got even better with the DGF. I’m basing this on the fact that two of the sites that I saw them at were ‘new’ and I also saw ‘multiples’ at Larkhill! Even more impressive than this I finally bagged a Larkhill DGF photo! In fact they were in good numbers at all sites so when I think about the DGF I’m left with a much more cheery feeling. Again this year I was struck by how different the genders appear. The earlier males appear two tone, black and vibrant orange whilst the later emerging females are often straw coloured with greenish-purple near the body and the sub-marginal spots can be almost white.
25 Silver-washed Fritillary, 17-07-2016 Bentley Wood
Almost a fortnight later this year although that could have been because I was away for a week of that time in Iceland and so didn’t manage to get out for that fortnight. Mind you when I did get to see them it was a petty mixed bag. On the positive side I found one at The Devenish again which suggests that my first there wasn’t just a one off and the Silver-washed is present in the Woodford Valley. Also on the positive side I found a Greenish again this year, I’m having a good run with this form. Unfortunately we now get to the negative, it’s bigly, sad (sorry too much Trump). I don’t think I’ve ever had a worse year for this species. True I didn’t get to Bentley as much as usual but even when I did they were so few and far between that I only managed a handful of shots.
26 Marsh Fritillary, 15-05-2016 Marshie Site
It’s hard to judge the fortunes of this species as they are in such large numbers. Whilst there were still loads around it felt like they were slightly down on last year – perhaps owing to their success. Thy do have a boom and bust population dynamic and so after a few years of boom perhaps this year was a little bust, not a full on collapse though, more pf a slight dip. I saw my first 2 days later this year although they had been flying for a while. Then a few weeks later on a visit with Philzoid we still found good numbers but there were still some caterpillars crawling around the ground – possibly because they didn’t find enough food and so developed too slowly? Hopefully after a year of lower numbers the balance will shift and they’ll be up in 2017.
27 Glanville Fritillary, 22-05-2016 Hutchinson’s Bank
I didn’t see this species in 2015 and so I can’t make any comparisons. Also I finally bit the bullet and made it to Hutchinson’s Bank to see the released population. I have had qualms about this before but then it’s a shorter trip to get to this site compared to the Isle of Wight and visiting here means less pressure and disturbance on the truly native population. Also with only one site remaining for this species it’s good to have a safety net should there be a disaster on the Isle of Wight.
Personally I’d love it if a female travelled across the Solent and the now extinct mainland colony was re-established as that’s even closer!
Have a goodun
