Aberbargoed Grasslands NNR, South Wales. A timely visit to do a
Marsh Fritillary larval 'survey' and I'm pleased to say that I saw 60+ during my morning visit, once the sunshine had warmed the critters up it became increasingly more difficult to find them, their undoubtably well dispersed throughout the main 'core' area though, the munched Devil's Bit Scabious was testament to this! I didn't have enough time available on this visit to 'survey' the other 'meta populations' within the reserve, but hope to return later in the week - not enough hours in a day this time of year
It was a delight to carefully tip-toe among the grasses searching for larvae while the Tree Pipits performed their wonderful sky dance above the Silver Birch and Chiffchaff and Blackcap provided nature's music in the background, mornings like this are simply magical

The grasslands seem to hold a very healthy Common Lizard population and I've long wondered if they snack on MF or their larvae, having said that those protective spiracles (or whatever) might make an attempted meal somewhat unpalatable, but then again some warblers seem to manage. Last year I saw and photographed a Common Lizard here more than 5" in length - now that's some potential predator
Perhaps I'm being a little pedantic but the recently erected Mission Butterfly signs at the reserve for visitors (and kids in particular) show a cartoon like butterfly being chased by a net, I don't think this is the right message to send out on a reserve that supports one of Europe's most threatened butterflies, ill informed visitors might just think that its okay to let their kids loose with a net

Whatever there are other positive things hapenning at the reserve including a new car park and metalled road, which is found as soon as you turn off the main road into the reserve* and its now clearly signposted too...so well done to Caerphilly County Borough Council for all the work so recently completed.
