A client of mine showed me that there was a lot of fly activity after these shrubs "flowered" which was a first for her. After this flies gathered to all the new growth they became attached to the underside and remain to this day. this was about a week -10 days ago. Has anyone ever seen this type of "attachment" from flies before. I realize some shrubs may emit something that attracts pests. I relayed that there is not a need for a pesticide or fungicide since the insects did no damage. But I wanted to get a second opinion too. The plant overall looks quite healthy.
