Hello,

I had the luck to see and photography Strepsiptera Stylopidae males and even to photography males in copula on the abdomen of Andrena bees.

I made a page of this, to be found at :

Hi Pierre,

A very nice find of this intruiging group of insects!
The species inside the Ancistrocerus is not Stylops melittae, which is confined to Andrena hosts, but rather Pseudoxenos heydenii.

Hello,

Thanks for the kind words.

I'll correct the page about the Ancistrocerus' parasit not being a Stylopidae, but rather a Xenidae.

Hi Pierre,

Well Xenidae, not everybody follows that split of families...
In my papers it is still under Stylopidae.
But those are just details! Grin

Best wishes,

John

great webpage.

For me it is so easy to spot them. Smile I have seen thousands male strepsiterans. awkward On Larinioides's web! Grin Thousands (here)is not a metaphor, it is the truth. Grin I always thougth them as very common insect. Smile
I have one photo that shows the female strepsiteran on abdomen of a Polistes ( the signal of her... not really her Grin)

I have caught only two specimens in over 1100 days of malaise trapping here in Greece, I would love to know what they are if anybody is able to determine them I will happilly send the specimens to them.

Gordon,

The specialist is Jeyaraney Kathirithamby (in Oxford).
On an Apidae list, she was told to welcome specimen in alcohol (see her page at http://users.ox.a...

I used to see adult males semi-regularly when I still used light to attract moth in my parents garden. Too bad I didn't know then that they are rather rarely collected.

Hello,

Thanks to all for the kind words. It really makes me happy to spend those hours looking for something to photography in my cemetery. But nevermind.

@Jorge:
Why don't you show some of those pictures? We dipterists are rather open-minded...

@John
Sorry for not mentionning you. I should have done it, since you were mentionned in the list I was speaking about.

@Kahis
We had a thread, on this forum, about a specimen caugth in a Malaise trap, some months (years?) ago. Those "little" orders are always rather funny as a way to relax a little.

Pierre, I don't have the photos of strepsipteran. But I will take photos, ok?

But for now I will show you a very ancient photo I took to a Polistes with my ancient nikon coolpix.
if you see in right part of abdomen it is possible to see an edema caused by a female strepsiteran.

I must wait for more warm weather so I can spot them! And then I will take some shots. But remember: they will be dead males on the web...

My thanks to Pierred for the info, but as I am already sending my Tephritids to John I will simply add the two tubes of Streps to the bag when it goes out.

I've got several Aculeate specimens with either female Stylops or empty male Styops pupa present, but I have only ever seen one male "in the wild". This was blown onto my car windscreen on a windy day just as I was starting up. Unfortunately, before I could do anything more than stare at it and say "wow - a Stylops" the wind smashed it to bits.

I will be checking out spiders webs near Aculete colonies this year though.......

Hi all,

@ Pierre,
No need to say sorry!

@ Gordon,
Thanks for providing the opportunity to study the specimens!
If i understand you well, you are sending all in alcohol, right? That's good! Especially for the Strepsipterans.

@ Jorge,
This really is the first time I heard they can be found in spider webs!! Really looking forward to seeing photo's of it! And if you would be so kind as to put a few of them on alcohol for me, I'ld be greatfull!

The Polistes infesting species as well as the Andrena insfesting ones are quite common, the other species however are rather rare! There are still several Aculeate genera with strepsipteran's which I have never seen before: in Panurgus, Bembix, Bembicinus, Podalonia, Ammophila etc. Has any of you ever seen these?
Another species that is quite common, or at least suspected to be quite common is Halictophagus silwoodensis paraitising in Ulopa reticulata (Homoptera, Cicadellidae), which feeds monophagous on Calluna vulgaris. Here in the Netherlands it should be possible to see the males in april on Calluna. No idea if it can be found outside it's known range, i.e. Belgium, Germany, England and the Netherlands. So go look for it Wink. I have recorded this species new for the Netherlands last year, including pictures of females inside the abdomen of the Ulopa and a picture of the Ulopa reticulata, anyone who wants a pdf, just let me know. Could make the searching somewhat easier.

Dear John,
Yes my specimens are all in alcohol, hopefully the mountain traps i am running this year will yield more streps. I hope you will forgive me if not all the Tephritidae are Tephritidae, they will be things that are common in the trap and can be thrown out.

May I ask are you also doing the Ulidiidae for me, and if not can you suggest someone who can?

Hi Gordon,

No problem1 I am use to getting all kinds of stuff as 'Tephritids'.
I can do nearly all Tephritoidea for you (excluding Lonchaeidae!), so Ulidiidae, Platystomatidae, Pallopteridae (though Jan Willem does these for you I guess) and Tephritidae.

Would be nice if the mountain traps would yield more Strepsiptera!

Best wishes,

John

Recently Christian Schmid-Egger showed my Strepsipterans in alcohol that he got from Wolfgang Rutkies. Wolfgang made great photo series of copulations, see the pics in the HymIS gallery (http://www.hymis....tree_seq=7). Best wishes, Sundew
