Driving out from Stevenage I noticed lots of bushes in people's gardens, this looked promising and so my first stop would be at Waterford Heath.
NO, a bit at zero bushes found there, but easily distracted by the large amount of Teasels around I decided to pick some to take home to check for Endothenia larvae....more o that later.
Next stop was Panshangar Park, where this rare moth was last recorded on BROOM! So it must be here....somewhere....anywhere? All I found after 90 minutes of walking was Gorse and then I found some! Unfortunately no larval spinnings were observed.
Nevermind, a quick trip across the pond to where a large area of Bullrush were situated and a couple of quick snaps of the easy to find Limnaecia phragmitella (obvious from the huge clumps of frass exploding fro the head).
Now, back to the Teasels
I took 8 heads home, 1 had nothing in it, 5 had Endothenia gentianaeana (no anal comb and reddish head) larva inside, the other 2 had Endothenia marginana (blackish head, anal comb observed) larva inside.
All in all it was nice to get out in the fresh air for a couple of hours.

Interesting, what do you do next pot them up along with the teasel heads until a cocoon is formed

Hi Ron. I believe they form a Cocoon inside the teasel once they have finished feeding, should be easy peasy.
