Does any one now the technique to net Charaxes and Polyura species?
Every time I get A1 specimen by the time I corner it in the net and kill it already has rubbed tips.
Makes me frustrated and I don't want to catch this group anymore .
Any advice ?
Paul

If you're using traps, they're fairly tame when they're drunk. So if they haven't been in the trap for long it's usually pretty easy to inject them with some sort of killing solution (if they're large) or give them a hard pinch. I also usually just try to quickly collapse the trap net down on them so they can't flap around too much.

I just net and pinch them, like all other specimens.
True that you have to give a hard pinch otherwise it doesn't work.
They are very fun to catch as they are powerful fliers. They don't really damage in my net so I see 2 possible issues for you :
- you don't have a technique to "block" them fast enough inside your net (if your net is too short, it can be a reason)
- your net texture is not silky enough
Hope it helps

They are so powerful and they flap like crazy and I always worry when try to corner them I damage the wings so I wait until they come down or have stop for one millisecond. I have never caught one in bait trap. I think I should change banana/sugar to some rotting crab or stinky fish sauce ( naam pla ( Adam will know what I am talking about)). Paul |

I have more this kind of issue with powerful small Lycaenidae which have very fragile scales like Lycaena alciphron.

Paul said: I think I should change banana/sugar to some rotting crab or stinky fish sauce ( naam pla ( Adam will know what I am talking about)). Assuming you don't want to use faeces (and I don't blame you for that  ) probably the best bait for Charaxinae is rotting (preferably marine) crab juice. Put some smashed crabs in water and leave them for a few days, then use the juice (warning you need a nose plug as it smells awful). I tried using Nam Pla (Thai fish sauce) instead of urine on muddy stream banks in Laos, but it only attracted bees. My friend said that it is quite good for Nymphalidae when splashed on the ground in the forest, but not good on stream banks. Adam. |

On stream banks, simple human urine also works well for Polyura in New Guinea.

Nam Pla works for some Nymphalidae and indeed it doesn't have to be near streams. I pour urine and nam pla beside and Papilionidae, Pieridae and Lycaenidae go to urine, Charaxes and Polyura also some numbers of Lycaenidae go to nam pla. Paul PS. Dead crab left on the sun for one day works as well, just step on it to let the juice come out, some butterflies like somtam too . |

Adam. the problem of dung and crabs is that only attract males .... sweet alcoolic food such as fermented bananas (or other fruit) attarct males and females ... and you can taste it yourself  |

Paul,
My wife and yours both like somtam, and I can imagine that some butterflies would be attracted to the fermented fish and crab juice that is included in the recipe.
For those of you (most I expect) who don't know what somtam is, it is basically a type of salad made from diced raw papaya fruit mixed with chilis, fermented fish, crab, lime and other ingredients. It is one of the staple dishes in NE Thailand and Laos. I don't eat it myself, but millions do.
Adam.

how long should you let the fruit ferment before its usable? are we talking a couple of days, 1 week or 4 weeks, etc?

Thanks for pointing this out, as it's very important. I "close it up" with a lid that has had a fair number of holes punched through it. |
