grab a magnifying glass and look underneath the leaves... if you have them you should see them.... sometimes when we get up and personal with our ladies... the hair on our heads can be very attracted to our girls and a few strands can give the appearance of a web.. or it could be an ordinary spider... when I had the borg.. could see the feckers as plain as day and the eggs... one blast of harkers harka mectin and they was dust..a good loupe would be better than a magnyfying glass but should be able to see em with a decent magnifying glass... dont let these feckers get a hold...easily sorted with ivermectin which is cheap as chips.
