Lesser Narcissus fly
« on: October 08, 2009, 10:55:54 AM »
Since I found Lesser Narcissus fly grubs in a bulb I have kept them with the bulb in a camera film case beside my monitor. This morning they are climbing the sides. I guess that by keeping them inside they have grown very quickly and want to pupate. In a few weeks I'll have a good idea of what they look like.

That's the idea, Lesley. All grubs/maggots have now left the unrecognisable bulb and gone underground. Specimen bottles come in handy for other things

My limited experience with the lesser narcissus fly revealed that there are a great many grubs in one bulb. This is in marked contrast to the greater narcissus fly, which rarely has more than one grub to the bulb.

One wonders if they bit a hole into the space time continuum to connect with an alternate universe filled with L.N.F. grubs, which then leak through to join their brethren in this universe.

The first Lesser Narcissus fly hatched today. They are very small, brown and only 5mm long. I have no idea how we can look for them among our bulbs. When it's wings expand and dry I'll torture it to make it buzz.  :o

Hi all ,

not so good news from me ....
Yesterday I found on one of my pots also such a animal ( I have in winter a lot of pots with seedlings in my room ,together with some evergreen Hippeastrum and some plants from southern hemisphere for changing her cycle )

I enclose here a pic ( sorry not so perfect )

Now my questions :
Is this a adult fly which comes from outside to lay eggs on my plants ?
Or is this a young fly which comes from one of my pots ?

It is for me the first time that I have seen this animal ( I know only the larvae )
This animal was very slow ( not flying ) - so no problem to catch it .

Any ideas ?

Hans,
The season for narcissus flies outside is spring - it seems your fly is your own breeding forced by artificial heat.

Freshly hatched flies are usually very slow and mostly unable to fly. This very young ones are not jet able to breed. ;D

This is a Narcissus fly. What has happened is the adult laid eggs during May, June and July on your plants. The grub feeds all summer and possibly during winter if the ground temperature is warm enough. Just like the Lesser Narcissus fly I have in a bottle beside the computer the maggot thinks spring has arrived and emerges. They are slow when they appear above ground.
