Brown Hairstreak on wild plum?

[peterc]

Has anyone witnessed Brown Hairstreak eggs or larvae on wild plum, Bullace Prunus domestica in the UK?

Someone reported seeing a female BH in a neighbour's garden near Mardley Heath, about 4 miles south of Stevenage, earlier this year. Follow-up visits from various people yielded more possibilities of BHs flying in the area. However, there is very little blackthorn in the immediate vicinity but loads of it 3 miles away, in Knebworth Park for instance. The splendid film by VarWIld taken in south France features some females laying eggs on wild plum - video clip on YouTube. I am wondering if wild plums in the Mardley Heath area are used for egg-laying and therefore worth investigating? Any thoughts?

Pretty sure Bullace is used at Steyning

Thanks, Paul. Several text books mention Bullace as an alternative food-plant without being too specific, e.g. height on which most eggs are likely to be laid. Interestingly, according to Emmet & Heath's 'The Butterflies of Great Britain and Ireland' book, 'In captivity, wild plum Prunus domestica is readily accepted and tends to give rise to larger specimens'.

Yes, there is a single specimen of wild plum at Chambers Farm Wood in Lincolnshire, where Brown Hairstreak is plentiful. The wild plum is used almost every year by egg-laying females. I also found a single Black Hairstreak egg on it a few years back.

Thanks for letting me know, Pete.

Bullace is used at Steyning too - I think Neil may have said that it is the preferred foodplant here. See http://www.sussex-butterflies.org.uk/sp ... streak.php

Hi all
Just caught up with this thread.
As others have said, Brown Hairstreak will readily use Bullace and there is indeed a preference over Blackthorn at Steyning. Other species/subspecies and varieties of Prunus are also used, including Victoria Plum.

Thanks, Neil.

Are Bullace and the other plum subspecies the preferred choices generally in the UK? Fascinating stuff.

Hi Peter,

The short answer is no. I can only say that Bullace is preferred to Blackthorn at Steyning (where I have sufficient data); the availability of Bullace will vary hugely from site to site, with many locations containing Blackthorn alone. The other types of Prunus I mentioned, including 'ornamentals', will be used on the relatively rare occasions when a wandering female will come across them (e.g. a Victoria Plum growing in a semi-rural garden), but there's no evidence I know of to suggest that Brown Hairstreak prefers these plants.

The eggs found on Hawthorn in Kent, shows that they will lay on other species as well, it was more than one egg as well, although most were on Blackthorn in that location, it was a pitty that the hawthorn eggs had to be moved as they were about to be cut off in Bridleway cutting work so they couldnt be monitored as larvae.
