That just means russia moved more of these things in range.
Ukraine destroys anything coming close enough to them. So this graphic mainly shows russian activity than ukrainian.
Having said that, the warming weather extends battery life and thus drone range and thus the kill zone.
Ukraine dramatically increased their production capabilities for drones of all kinds. Every other month a New Production line goes online, in ukraine or in the EU.
They now have enough to intercept 2000+ drones daily, AND still export drones and operators to the middle east.
You can also bet that they have enough stockpiled for themselves and probably are secretly equipping baltic states to counter a russian aggression against them.
russia faces increasingly scarce ressources while ukraine’s capabilities will continue to grow during the year.
Almost 1500 losses…
Someone miserably failed in an offensive again…
