Today I noticed that a few of the garlic plants in my garden looked a little sorry for themselves. On closer inspection I noticed a few white marks on the outer leaves of each plant. Each of the white marks had a hole in it. Peering inside the stems I saw a yellow maggot or larvae with a brown end or head happily eating away at the new leaves that the plant was getting ready to expose. I pulled each of the infected plants out - on second thoughts this might have been hasty.

Any ideas what these lovely little guys are and how I might stop them infecting the rest of my crop. I have grown garlic in the UK for many years without problems but I have now lost half of my first Texas garlic crop. Please help.
