So Tanyscelis ssp. (mature female gall) looks good. Id like to see some of the other 11 species.

I'll strap one of those sport cams to Lily's forehead. She'll share lots of spottings of alpaca poop and chickens (dog, afterall).

Maybe I was talking to the dog =)
You've gotta get a camera for that dog.

That cute little puppy below is me, btw, Martin. I signed in with the wrong account.

Wow. I haven't seen any like that around here. Nice one.

I added a dissection but no answers were exposed. Maybe the organism has come and gone.

The arrangement (in rows) makes me suspect an egg laying culprit like a wasp. I must do a dissection. (The flower gall contained some rather indecisive green tissue).

Nice spotting martin. It's amazing how many different types there are. This one is a little like the fingery ones I found.

This is growing on a young Eucalyptus but I am not certain of the particular species.
