No Stichophthalma?  I guess it would be difficult to grow the bamboo they feed on in a UK greenhouse. Adam. |

No Stichophthalma? I guess it would be difficult to grow the bamboo they feed on in a UK greenhouse. Adam. Sadly not Adam, though I do have a couple of bamboo species growing in the garden, Phyllostachys aureus and bissetii, the first growing 4m high and Stratford butterflies have listed Stichophthalma howqua pupae from China so you never know, one day maybe. I have had no luck with the greenfly issue, I have sprayed several times with 5% milk and still they survive, I think this year I may have to forget the breeding and use a systemic pesticide, the docks, violets and blackthorn are all showing deformed leaves as the aphids are over powering and sucking the sap. I have one I use in the garden which lasts a few weeks so it should kill off anything in there this year but should have cleared by next spring, hopefully the plants will put out plenty of fresh, aphid free growth buy then and I'll start afresh. I only have these two species in there and the Black hairstreak over winters as an ova and the Silverwashed over winter as a newly hatched larvae (without feeding) so if they do breed in there, they may survive the pesticide and be present next spring.

Rich,
Sorry to hear that the milk treatment isn't working. I heard that it does the job really well. Alternatively try spraying them with washing up liquid. If you do resort to an insecticide I would recommend that you try to use a non-systemic contact insecticide with low persistence. I sometimes use Lannate here if really necessary. If treated plants are washed they can be safely used in less than 2 weeks.
Adam.

The only trouble with a none systemic is getting them all, I thought I had checked all plants carefully, the great water dock and common dock plants had all leaves removed and fully submersed for 2 days prior to going into the green house, the trees had no leaves on and were wiped with a clean damp cloth, the rest grown from seed and now it's an infestation, there couldn't have been that many to start with, but then it doesn't take many with how fast they breed.
I'm thinking once the butterflies in there have died off i'll use a systemic pesticide everywhere in August then after a couple of weeks remove all the leaves and leave the plants closed up untill next spring, as I won't be looking for any livestock untill April/May they will have at least 8 months from treatment, the pesticide I use on my clematis for aphids only lasts a few weeks, I know this for a fact as I've often had to re spray them throughout the season.

About 20 years ago I was working with a company in Florida the grew orchids. The had sticky strips (Glue boards) hanging in large numbers in every green house to control Aphids. I remember the boards were fairly clean. When I questioned one of the Botanists I was told the Sticky Boards had a Pheromone that attracted Aphids and they were deployed 24/7/365. If removed for a week the house would be overwhelmed with Aphids.
I also know (and don't know how I learned) that Aphids are a serious problem in green house Tomatoes. After each harvest the green house is bombarded with pestcides.

Just spotted these in amongst the foliage..  Had to take a quick snap as I took the photo with the door open, didn't want to disturb them by going into the greenhouse as they are perched inches from the door. Rich |

I have 6 female silver washed fritillaries busy laying eggs, I have sleeved 2 over common dog violets the other 4 I left in the greenhouse, the main reason I separated them is because I am going to use a systemic insecticide as soon as these Frits die off to try and eradicate the aphids infestation, all the violets in the greenhouse have died off, thanks to these little sap suckers, the eggs from the 2 sleeved females are outside and won't be sprayed so hopefully I'll have some survive from these, those in the greenhouse should be ok, most are on the timber framework and netting in the eaves of the structure so won't get sprayed, also as this species hibernates as a small larvae straight after emerging, they don't eat untill next year, when hopefully the next lot of violet seeds will be rampant and insecticide free (it's only active for 6 weeks).
It's been great to see this large fritillary flying in my greenhouse this year, yes they do spend quite a while clinging to the netting in the roof but they also behave very naturally some times, early morning they are down low, perched in sunshine warming up, males have been seen searching around the small elm, blackthorn and cherry looking for females and now the females are searching out suitable egg laying sites (everywhere), hopefully I can repeat this next year and future years inbreeding and getting some nice abberations, also trying the high brown (A.adippe) and if I can find any livestock I want to try the pearl bordered frit (B.euphrosyne) though I haven't seen anyone selling livestock of these.
I'm still hoping for Speyeria diana if anyone can get eggs.

I'm over the moon to get these this year, I have half a dozen small egg batches so far, I only have 2 females in my collection from Tenerife and 1 from La Palma, so resisting the temptation to set these was hard, however it looks like I will be rewarded, I got 13 adults from a batch or 14 eggs ( one egg didn't hatch) so can't be bad. I will rear as many as possible but I hope to get another generation after these, they are continually brooded with no diapause so I have some winter cabbage growing on to try and keep a small colony going through the winter. These are larger photo's of some superb individuals..      Rich I love the hindwing colour on the first female.. |

I agree Joe, though I admit I have very few in my collection, a series of these should look great if I manage to breed plenty, though these eat cabbage they are only laying eggs on the nasturtium plants in the greenhouse, even though there are several of the cabbage plants that I reared them on in there, I've also read that they lay on the underside but I probably have a dozen small groups of eggs now on the top side of the leaves.
