Hello

Can anyone confirm if this puparium is from the tomato leaf miner (Liriomyza bryoniae)? Millimeter scale on left.

After taking a closer look in a better microscope I am now pretty sure it is Liriomyza nietzkei.

How are you able to determine the species of this agromyzid using the puparium stage alone? Are you using characteristics of the spiracles? Just curious.

Yes, I found figures of the spiracles in the reference below (Spencer named it in 1973) and compared the specimen with the spiracles of all the Liriomyza species I could find in the litterature. Several could also be excluded as they are neotropical and not found here etc. Liriomyza nietzkei was the closest match by far although I haven't been able to find figures of the spiracles from all the species in the genus. The specimen was found in a latrine so it also seems logical that it probably has something to do with food - Liriomyza nietzkei is a pest of onions and leek so it seems likely on that account as well.

Very interesting, thanks for the explanation. I have spent a good deal of time attempting to photograph posterior spiracles of puparia in various families as part of my studies of stem-dwelling insects. Unfortunately I don't have access to a good dissecting scope or similarly high-powered magnifying tool to really dive into the intricacies; the most detailed spiracle photos I get are a bit less zoomed-in than what you posted here. Best of luck with your latrine fauna investigations - it sounds like an intriguing line of study.

Taking good pictures of the spiracles is always hard. Even a slight adjustment of the specimen or the angle of the light source can make a huge difference. The ones posted here of the spiracles are 100x magnification, which is the limit of my stereoscope, and you can just barely see the papillae on one of the pictures.

Thanks, good luck with your studies as well.
