ladybird egg?!?!?

sorry guys but i don't know where to post it so considered is link to my veg i posted here..
this years i don't know why all my tomato and squash and almost all my plant are free from aphid and just few greenfly but i daily squish them..but when i sow lettuce lollo rossa and little gem and alpine strawberry they are covered of them... my lollo rossa is lollo verde instead..( verde is green in italian) so what i've done is leave some of them ( considered that i have a lot that i don't know what to do e where to put them) i left them in the blowaway waiting for some miracle... the miracle is happen... this morning i found a ladybird and i tried to catch her but she flow away... this afternoon i went again in the garden and i found around the blowaway frame a lot of yellow dot and some on the alpine strawberry... are they eggs or not?what i have to do now? get ready a welcome party for them stoppin squish all the aphids or cary on with the routin?
