Time to stand and stare, time to study nature? Brimstone 3 ….

A large proportion of the brimstone ova have changed colour to a yellow with a more recent ‘white’ ovum present alongside a few of them, perhaps an example of what Frowhawk had described and mentioned in the ‘brimstone update’ of 29 April.  The batch of four are still present, as are the three with pairs and singles a plenty.

Click on the image above to see three yellow and one white ovum, two on the mid-rib and two on veins.

I’ve even managed to locate some more ovum on another alder buckthorn plant further south in the hedge.  The leaf buds are not as far advanced as those with the larger numbers of ova already present.  What is interesting is that one leaf bud has three ova which look as if they were laid at the same time, the leaf bud is still quite tight with no sign of an open leaf and one of them is actually on the stem not soft leaf tissue (click on the image below to enlarge).

Both male and a female brimstone were observed in the general area but not seen to show an interest in each other or in prospecting the hedgerow for new sites to egg lay.

Other insects active were numerous Large Red Damselfly and what appears to have been a gathering of Nomada sp. or ‘cuckoo bee’ (quaintly referred to as a social parasite) around a burrow entrance under coppiced hazel bushes …. BWARS is an excellent website to try to establish their identity as it has some good images, as does Eakringbirds (another excellent website) and whilst BWARS offers distribution data the species text is not yet available.  Of around 30 Nomada species I have it narrowed to three possibilities and only one appears in Skidmore (2006) so watch this space for an update.
